Abstract
The fiber-optic module includes the optical element and the conjugant on the fiber element side. The invented method provides the conjugant with bulge on the joint face, which is fixed on the optical element. With the optical element and the conjugant on the fiber element side being aligned, electrical current is applied to melt the bulge so as to connect the conjugant on the optical element side with the conjugant on the fiber element side. Comparing the fixed form with glue, the method prevents the jointed deflection caused by the influences of temp, humidify or chemical reaction. Since the cost of the resistance welder is cheaper than the cost of the laser welder, the method possesses advantage of fast producing speed.
Description
Technical field
The present invention relates to a kind of optic module and manufacture method thereof, be meant especially to be used for optic module and manufacture method thereof luminous or reception light.
Background technology
Along with spreading of world-wide web agitation, the boundary in the virtual world that network is constructed and the human entity world is more and more fuzzyyer, and structure is shared based on the world-wide web data and the low characteristic that enters obstacle, network application miscellaneous has appearred in the actual life, for example shopping at network, finance business on network, video conference, action office etc. are commercial to use, or non-commercial application such as data search, Online Learning, network on-line recreation, remote medical-treatment.Present world-wide web not only can provide the daily life of the human overwhelming majority required, simultaneously also for bringing up unlimited possibility future.
And be accompanied by various application and development on the network, at first the problem that will solve is the problem of frequency range deficiency, and take a broad view of various medium of communications, wherein can meet demand with optical fiber, its have frequency range height, decay low, be not subjected to Electromagnetic Interference, confidentiality is good, volume is little and characteristic such as in light weight, make it become first of medium of communication and select, big to intercontinental subsea cable, network backbone, little of school's network, company's special line, or even the household of community, actively use optical fiber to carry out communication invariably.
Most important element in the middle of the optical-fibre communications is optical transceiver (OpticalTransceiver), and it is a mutual conversion work of being responsible for light signal and electric signal, and key part and component wherein, be optic module, for example light receiving and transmitting submodule (OSA, OpticalSub-Assembly) etc.Please refer to shown in Figure 1ly, existing optic module is made up of an optical element 11 and a cannulated sleeve 12, and this optical element 11 plugs together in cannulated sleeve 12, and fixes in the mode of gluing, and its error amount is about 20 to 30 microns (micron).The shortcoming of this kind practice is that colloid partly is subjected to the influence and softening the going bad of temperature, humidity or chemical reaction easily, causes the skew of three dimensions (X, Y, Z-direction), and then causes the loss of light signal.Because this kind optic module has above-mentioned shortcoming, is do not need in the light signal transmission system of pinpoint accuracy to apply to mostly with it.
For improving this kind situation, the dealer is developed again and laser welding technology recently, and it is that optical element is socketed in the conjugant, and with itself and (not being shown in figure) that sleeve combines in the mode of laser bonding, its error amount is about in 1 micron again.This kind mode is no doubt effectively improved gluing mode Yin Wendu, humidity or skew that chemical reaction caused, but the board of laser bonding involves great expense, and causes cost significantly to rise, and is unfavorable for quick and a large amount of production.
Therefore, in sum, how to provide a kind of accuracy height, cost is low and be not subject to temperature, humidity or chemical reaction and cause the optic module and the manufacture method thereof of skew, is the problem of needing solution badly in fact.
Summary of the invention
At the problems referred to above, purpose of the present invention is for providing a kind of accuracy height, cost is low and is not subject to the method for manufacturing fiber-optic module that temperature, humidity or chemical reaction influence.
For reaching above-mentioned purpose, the optic module in the method for manufacturing fiber-optic module of the present invention comprises an optical element, and an optical fiber side joint zoarium in order to engage with a fiber optic component.The optical element side joint zoarium that provides a composition surface to have protuberance is provided method for manufacturing fiber-optic module, and it is itself and optical element fit is affixed, follow align optical components and optical fiber side joint zoarium, apply the protuberance that electric current melts optical element side joint zoarium at last, to fuse the fit and optical fiber side joint zoarium of optical element side joint.
In addition, the present invention also provides another kind of method for manufacturing fiber-optic module, wherein optic module comprise an optical element, and one with the affixed optical element side joint zoarium of optical element fit.Method for manufacturing fiber-optic module comprises provides one in order to engage the optical fiber side joint zoarium that a fiber optic component and composition surface have protuberance, follow align optical components and optical fiber side joint zoarium, apply the protuberance that electric current melts optical fiber side joint zoarium at last, to fuse the fit and optical fiber side joint zoarium of optical element side joint.
Because method for manufacturing fiber-optic module of the present invention, it is element with the mode fusion welding fiber module of resistance welded, so can improve the influence of gluing fixed form Yin Wendu, humidity or chemical reaction, and generation is with respect to the situation of the skew of other two-dimensional space (being X, Y direction) of direction of engagement, simultaneously, the cost of resistance welded board is also much smaller than the laser board of costliness, therefore can reach accuracy height, cost low, be not subjected to the influence of temperature, humidity or chemical reaction and cause skew, and be beneficial to quick and a large amount of production.
