Abstract: The present disclosure is generally directed to an optical transceiver that includes a multi-channel on-board ROSA arrangement that includes an optical demultiplexer, e.g., an arrayed waveguide grating (AWG) and an array of photodiodes disposed on a same substrate. The array of photodiodes may be optically aligned with an output port of the optical demultiplexer and be configured to detect channel wavelengths and output a proportional electrical signal to an amplification circuit, e.g., a transimpedance amplifier. Each of the photodiodes can include an integrated lens configured to increase the alignment tolerance between the demultiplexer and the light sensitive region such that relatively imprecise bonding techniques, e.g., die bonding, may be utilized while still maintaining nominal optical power.

Abstract: Techniques for flexible coupling between an optical coupling receptacle/port of an optical transceiver housing and optical components within the same are disposed. In an embodiment, an optical transceiver housing includes an intermediate fiber with a first end optically coupled to an optical coupling port and a second end optically coupled to a multiplexer/de-multiplexer device, e.g., an arrayed waveguide grating (AWG) device, PLC splitter, and so on. The intermediate fiber may be routed in the transceiver housing in a manner that and the radius of the bends may be optimized to reduce fiber bending losses. The techniques herein are equally applicable to both ROSA and TOSA modules and may be utilized to achieve flexible coupling for multi-channel transceiver devices.
