Abstract
The present disclosure is generally directed to an optical demultiplexer for use in an optical transceiver module having a truncated profile/shape to increase tolerance and accommodate adjacent optical components. In more detail, the optical demultiplexer comprises a body with at least one truncated corner at the input end. The at least one truncated corner allows the optical demultiplexer to be disposed/mounted, e.g., directly, on a densely populated transceiver substrate, e.g., a printed circuit board (PBC), and provide additional tolerance/space for mounting of circuitry and/or components within the region that would normally be occupied by corner(s) of the optical demultiplexer body. The at least one truncated corner may be introduced in a post-production step, e.g., via cut & polishing, or introduced during formation of the optical demultiplexer using, for instance, photolithography techniques.
