Abstract
The utility model relates to a miniature wavelength division multiplexer (WDM), which comprises a rectangular prism, a diaphragm arranged on the surface of the rectangular prism, and at least one incident collimator and at least one emitting collimator both arranged on the rectangular prism. The incident collimator and the emitting collimator are arranged on the rectangular prism in a parallel manner. The rectangular prism is also provided with a reflection unit. The light of the incident collimator and the light of the emitting collimator adjacent to the incident collimator are converged at one point on the reflection unit, wherein the angular bisector of the angle formed by the above light is vertical to the reflection surface of the reflection unit. Meanwhile, the angle of the incident light of the diaphragm needs to be fixed, and the angular bisector of the angle formed by the light of the incident collimator and the light of the emitting collimator adjacent to the incident collimator is vertical to the reflection surface of the reflection unit. In this way, the requirement on the incident light of the diaphragm can be met. Therefore, all the collimators are in a parallel arrangement, so that the dimension of the WDM is greatly reduced.
Description
Technical field
The utility model relates to a kind of optical component, more particularly, relates to a kind of miniaturization WDM.
Background technology
Having the CWDM scheme now is, as depicted in figs. 1 and 2, incident light incides right-angle prism 6 from collimating apparatus 1, and incident light is at the light beam of the wavelength of diaphragm output outgoing collimating apparatus 2 correspondences of outgoing collimating apparatus 2 bottoms, and all the other light reflections are to next outgoing collimating apparatus; The light beam of the wavelength of diaphragm output collimator 3 correspondences of outgoing collimating apparatus 3 bottoms, all the other light reflections arrive next collimating apparatus, the like.From 1 incident of incident collimating apparatus, from collimating apparatus 2,3, the light path that 4,5 outgoing are the demux device; If direction is from collimating apparatus 2,3,4,5 incidents, close the light outgoing from collimating apparatus 1, forms the light path of mux device.Incident diaphragm angle is by the incident angle assurance of incident collimating apparatus, and now incident becomes splayed separately with the outgoing collimating apparatus.
The shortcoming of this light channel structure is:
Because this structure light path turnover realizes by a right-angle prism, and diaphragm incident need to have a fixing angle+θ (+θ or-θ can), finally caused incident collimating apparatus and outgoing collimating apparatus to produce angle with respect to the both direction of right-angle prism normal.This kind of structure incident and outgoing collimating apparatus are separated to both direction respectively.The horizontal volume guarantee collimating apparatus and the optical fiber that now need greatly to increase housing are not impaired, and this kind of structure is difficult to adapt to the optical communication trend of miniaturization increasingly.
The utility model content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of miniaturization WDM.
The utility model solves the technical scheme that its technical matters adopts: construct a kind of miniaturization WDM, comprise right-angle prism, be arranged on the lip-deep diaphragm of described right-angle prism, and at least one is arranged on incident collimating apparatus and at least one outgoing collimating apparatus on described right-angle prism, described incident collimating apparatus and outgoing collimating apparatus are arranged on described right-angle prism in parallel to each other, and also be provided with a reflector element on described right-angle prism, by described incident collimating apparatus, and the light of the described outgoing collimating apparatus adjacent with described incident collimating apparatus pools a bit on described reflector element, and the angular bisector of the angle formed by these light is vertical with the reflecting surface of this reflector element.
Miniaturization WDM described in the utility model, wherein, described reflector element is the wherein reflecting surface on edged surface always that is arranged on described right-angle prism.
Miniaturization WDM described in the utility model, wherein, described reflector element is the wherein wedge reflector on edged surface always be convexly equipped with at described right-angle prism.
Miniaturization WDM described in the utility model, wherein, described reflector element is the wherein wedge reflector on edged surface always be arranged with at described right-angle prism.
Implement miniaturization WDM of the present utility model, there is following beneficial effect: because diaphragm incident need to have a fixing angle, and vertical with the reflecting surface of reflector element by the angular bisector of the light angulation of incident collimating apparatus and the outgoing collimating apparatus adjacent with the incident collimating apparatus, guaranteed the angle of diaphragm incident requirement, so just each collimating apparatus can be arranged in parallel, thereby greatly reduce the size of device.

Embodiment
As shown in Figure 3 and Figure 4, in preferred embodiment of the present utility model, this miniaturization WDM comprises right-angle prism 300, be arranged on the lip-deep diaphragm (not shown) of right-angle prism 300 and at least one is arranged on incident collimating apparatus 100 and at least one the outgoing collimating apparatus 200 on right-angle prism 300.Wherein, incident collimating apparatus 100 and outgoing collimating apparatus 200 are arranged on right-angle prism 300 in parallel to each other, and also be provided with a reflector element 301 on right-angle prism 300, light by incident collimating apparatus 100 and the outgoing collimating apparatus 200 adjacent with incident collimating apparatus 100 pools a bit on reflector element 301, and the angular bisector of the angle formed by these light is vertical with the reflecting surface of this reflector element.
Because diaphragm incident need to have a fixing angle θ, and vertical with the reflecting surface of reflector element by the angular bisector of the light angulation of incident collimating apparatus 100 and the outgoing collimating apparatus 200 adjacent with incident collimating apparatus 100, guaranteed the angle of diaphragm incident requirement, so just each collimating apparatus can be arranged in parallel, thereby greatly reduce the size of device.
Incident light incides right-angle prism 300 from incident collimating apparatus 100, and incident light is before inciding outgoing collimating apparatus 200, and diaphragm can be exported the light beam with these outgoing collimating apparatus 200 corresponding wavelength, and all the other light reflections are to next outgoing collimating apparatus and the rest may be inferred.From 100 incidents of incident collimating apparatus, the light path that is the demux device from 200 outgoing of outgoing collimating apparatus; If direction, from 200 incidents of outgoing collimating apparatus, is closed the light outgoing from incident collimating apparatus 100, form the light path of mux device.
Preferably, reflector element 301 can adopt the wherein reflecting surface on edged surface always that is arranged on right-angle prism 300.Perhaps, this reflector element 301 adopts the wherein wedge reflector on edged surface always be convexly equipped with at right-angle prism 300.This wedge reflector should have a plane of reflection can meet the angle of diaphragm incident needs.Understandable, reflector element 301 can be also the wherein wedge reflector on edged surface always be arranged with at right-angle prism 300.
