Abstract
The invention relates to a compact transmitter optical sub-assembly (OSA), which can be used in small form factor optical transceivers. To limit back reflections from entering the laser cavity, the laser is disposed on a silicon optical bench (SiOB) at an acute angle to the longitudinal axis of the OSA. A portion of the light from the laser cavity passes through the back end of the laser cavity for measuring by a monitor photodiode. A rear beam steering lens redirects the portion of light into a v-groove in the SiOB and off of a reflective surface formed in the end thereof to the monitor photodiode, which is positioned face down over the v-groove.
