Technical field
The utility model relates to the optical component in optical communication field, specifically a kind of free space isolator.
Background technology
Along with optical communication technique is towards two-forty, jumbo future development, the reflection existed in light path has become a major issue that must solve.Therefore occurred that a kind of allows light along the nonreciprocity optical passive component-optoisolator of forward optic path, can prevent the stability of reflected light influential system light source, ensured accuracy and the security of transmission light source (normally laser instrument).According to the polarization dependent behavior of optoisolator, isolator can be divided into polarization relationship type and polarization independent type two kinds, the former is also called free space type (FreeSpace) because of the non-fiber input and output of device two ends; The latter has optical fiber cable input and output because of device two ends, is also called at line style (In-Line).Free space isolator particularly has the function of isolation reverse interference signal for communication network sending and receiving end, to guarantee the stability of communication network, it is mainly used in semiconductor laser, because the light that semiconductor laser sends has the high linearity, the optoisolator that this polarization thus can be adopted to be correlated with thus there is the advantage of low cost.
As shown in Figure 1, current free space isolator mainly comprises magnet ring 10 and optical chip 30, fills full bonding agent 20 in magnet ring 10 and the assembling gap of optical chip 30, is fixed in the middle of magnet ring 10 optical chip 30 location by the bonding agent 20 of heat curing.
The free space isolator of this structure, optical chip 30 is in both sides sealed condition in magnet ring 10 inside, bonding agent 20 seals in the later stage and assembles and carry out in the process of hot setting, there will be its inner sealing side causes optical chip 30 in magnet ring 10, produce relative displacement because air expands, and finally causes free space isolator to depart from former rigging position.And the free space isolator of this structure needs by optical chip 30 pre-determined bit in the middle of magnet ring 10 and by bonding agent 20 2 injecting glues, complex operation, qualifying point increases, and affects product quality and production efficiency.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of optical chip to be in the free space isolator of both sides connected state in magnet ring inside.
In order to solve above-mentioned technical matters, the basic technical scheme that the utility model proposes is:
A kind of free space isolator, comprises magnet ring and optical chip, it is characterized in that,
Described optical chip is arranged on magnet ring inside, being fixedly connected with the inwall of magnet ring with at least one corner on the central axis of magnet ring side in the same way of described optical chip.
Further, the corner of described optical chip and magnet ring inwall have gap.
Further, four corners of described optical chip are fixedly connected with the inwall of magnet ring.
Further, the inwall of described corner and magnet ring is adhesively fixed.
The beneficial effects of the utility model are:
Being fixedly connected with the inwall of magnet ring with the corner on the central axis of magnet ring side in the same way 1, due to optical chip, thus make, between the side of optical chip and the inwall of magnet ring, there is space, the two ends of free space isolator are in connected state, so the sealing in the later stage of bonding agent is assembled and carries out in the process of hot setting, the air expanded passes through from space, greatly reduce the compressing to free space isolator, avoid free space isolator and depart from former rigging position, improve the quality of products.
2, because the utility model adopts, the corner of optical chip and the inwall of magnet ring are adhesively fixed, pre-determined bit and secondary injecting glue is needed when avoiding filling adhesive in the assembling gap of optical chip and magnet ring, install simple and convenient, qualifying point reduces, and can improve 10% production efficiency.

Embodiment
Below with reference to drawings and Examples, the utility model is described further, but protection domain of the present utility model should not be limited with this.
For convenience of description and understand the technical solution of the utility model, below illustrate that the orientation that the noun of locality used all is shown with accompanying drawing is as the criterion.
Embodiment one:
As shown in Figure 2, a kind of free space isolator of the present embodiment, comprises magnet ring 1 and optical chip 3.
As shown in Figures 2 to 5, the cylindrical ring-type of magnet ring 1, optical chip 3 is arranged on the inside of magnet ring 1.Optical chip 3 comprises two polaroids 31 and optical rotation plate 32, and optical rotation plate 32 is located in the optical chip 3 being superimposed as rectangular parallelepiped between two polaroids 31.Being fixedly connected with the inwall of magnet ring 1 with four corners 33 on the central axis of magnet ring 1 side 34 in the same way of optical chip 3.Corner 33 comprises and the central axis of magnet ring 1 rib 331 in the same way and the part 332 intersecting side corresponding to two of rib 331.Corner and the magnet ring inwall of described optical chip have gap.
Be provided with bonding agent 2 between the inwall of corner 33 and magnet ring 1, the inwall of corner 33 with magnet ring 1 is adhesively fixed by bonding agent 2, thus makes to have space 4 between the side 34 of optical chip 3 and the inwall of magnet ring 1, and the two ends of free space isolator are in connected state.Bonding agent 2 can be any optical adhesive.There is gap for providing the installing space of bonding agent 2 between the inwall of corner 33 and magnet ring 1.
