Abstract: PROBLEM TO BE SOLVED: To provide an optical sub-assembly positioning method for test. SOLUTION: In the method, the positioning of an optical sub-assembly 10 within a capture zone on the supporting face 40 of a fixing device for test is executed for a test. At least two probes 50 are engaged with the surfaces of respective reference faces 30, 34, 36, 38 accurately positioned on the surface of the sub-assembly 10. In a sutable example, a 3rd probe is brought into contact with one surface 16 of the sub-assembly 10 which is another reference face on the surface of the sub-assembly 10. When the probes 50 and the 3rd probe are engaged with the surfaces of respective reference faces and furthermore, moved in the directions of respective reference faces, the sub-assembly 10 is moved in parallel so as to more accurately match with an optical system in the fixing device for the test.

Abstract: There is disclosed, an optical subassembly (10) includes a platform (12) on which a laser (18) and photodiode (14) are mounted. The laser (18) has a rear facet (42) through which passes a small portion of the light emitted by the laser (18). The photodiode (14) is mounted on the surface of the platform with a light admitting facet (44) for receiving a portion of the light emitted from the rear facet (42) of the laser being substantially perpendicular to the light emitting facet (42) of the laser. The surface of the platform may include a channel (34). The channel (34) may be tapered from a narrower end (36) near the laser (18) to a wider end (38) near the photodiode (14), and may be coated with a light-reflective material.

Abstract: There is disclosed a method of positioning an optical subassembly (10) for testing includes positioning an optical subassembly (10) within a capture zone on a support surface (40) of a test fixture. At least two probes (50) engage surfaces of respective ones of precisely located fiducials (30, 34, 36, 38) in a surface of the optical subassembly. A third probe (72) contacts a surface (16) of the optical subassembly, which in a preferred embodiment may be another fiducial in the surface of the optical subassembly. Upon engagement of the probes (50, 72) with surfaces (58) of respective fiducials and movement of the probes further into respective fiducials, the optical subassembly is translated into more precise alignment with optics of the test fixture.
