CPC G02B 6/4246 (2013.01) [G02B 6/4257 (2013.01); G02B 6/4271 (2013.01); G02B 6/4281 (2013.01); H04B 10/40 (2013.01)] | 18 Claims |
1. An optical transceiver sub-assembly integrated with a silicon photonic platform having a folded optical path for transmitting and detecting a plurality of optical signals, the sub-assembly comprising:
a housing chamber;
a top cover configured to engage with the housing chamber to enclose elements in the optical transceiver sub-assembly other than the housing chamber and the top cover;
a bottom housing module accommodating an optical micro integration;
a transparent optical window to establish an optical communication with outside surroundings;
one or more slots are configured at electrical inlet and/or electrical outlet points on the housing chamber and the top cover; wherein the one or more slots are epoxy slots configured to hermetically seal the optical micro integration;
a plurality of fixing features at a bottom of the housing chamber to fix the bottom housing module;
a carrier configured to hold and provide support to the optical micro integration;
a thermoelectric temperature controller (TEC) deposited on the carrier for cooling heating elements in the optical transceiver sub-assembly;
the optical micro integration comprising:
an optical micro bench configured to deposit a photonic integrated circuit (PIC), a light source, a plurality of passive optical components and an inner printed circuit board (PCB), wherein a cooling surface of the TEC is placed towards the optical micro bench;
the light source emitting an output light signal and being a laser source;
the PIC manipulating a light beam to form and emit the plurality of optical signals to one of the plurality of passive optical components as an output passive optical component; and
a prism configured to fold the output light signal from the light source in a reverse direction from an original path;
wherein the optical transceiver sub-assembly is operably configured to establish an optical-electrical communication with the outside surroundings.
