| 英文摘要 | An apparatus and method for monitoring the optical output of vertical cavity surface emitting lasers (VCSELs) utilizes a portion of light emitted by the VCSEL (2) and scatters and/or reflects this portion of emitted light so that it is directed towards a detecting surface (9A) of a photodetector (8A). In one embodiment, scattering elements may be incorporated within the epoxy or other coupling medium (10) used to couple the VCSEL to the optical fiber (4). In another embodiment, the VCSEL may be coupled to an optical fiber secured within a ferrule (5) which has an end surface capable of reflecting or scattering light and directing the light towards the photodetector. In another embodiment, a reflective integrating member may be alternatively or additionally used to reflect a portion of the emitted light to the photodetector. The photodetector, in conjunction with electrical circuitry to which it is coupled, develops and electrical signal which may be provided to laser control means to control and adjust the optical output of the VCSELs. |
