摘要： Optical triplexers are disclosed. The optical triplexers include an optical fiber, a first ball lens optically coupling a first optical signal between a first opto-electronic device and a first wavelength selective filter, and a second ball lens optically coupling a second optical signal between a second opto-electronic device and the first wavelength selective filter. The optical triplexers further include a second wavelength selective filter optically coupling the first and second optical signals between the first wavelength selective filter and a third ball lens and a fourth ball lens optically coupling a third optical signal between a third optical signal between a third opto-electronic device and the second frequency selective filter. The second wavelength selective filter optical couples the third optical signal between the fourth ball lens and the third ball lens. Thus, each of the optical signals are selectively coupled between one of the opto-electronic devices and the optical fiber.

摘要： Multi-laser transmitter optical subassemblies (TOSAs) for optoelectronic modules. In one example embodiment, a multi-laser TOSA includes first and second lasers configured to generate first and second optical signals, respectively, a polarization beam combiner (PBC), first and second collimating lenses positioned between the first and second lasers, respectively, and the PBC, a half waveplate positioned between the first laser and the PBC, and a focusing lens. The half waveplate is configured to rotate the polarization of the first optical signal. The PBC is configured to combine the first and second optical signals and transmit the combined first and second optical signals toward the focusing lens.

摘要： Multichannel RF Feedthroughs. In some examples, a multichannel RF feedthrough includes an internal portion and an external portion. The internal portion includes a top surface on which first and second sets of traces are formed. Each set of traces is configured as an electrical communication channel to carry electrical data signals. The external portion includes a bottom surface on which the first set of traces is formed and a top surface on which the second set of traces is formed. A set of vias connects the first set of traces between the top surface of the internal portion and the bottom surface of the external portion.
