Abstract:
Methods and systems for a free space CWDM MUX/DEMUX for integration with a grating coupler based silicon platform may include an optical assembly coupled to a photonic chip. The optical assembly includes a lens array on the top surface of the chip, an angled mirror, a plurality of transparent spacers, and a plurality of thin film filters. The optical assembly may receive an input optical signal comprising a plurality of optical signals at different wavelengths via an optical fiber coupled to the optical assembly, communicate the plurality of optical signals through a first of the plurality of transparent spacers, pass a first of the plurality of optical signals through a corresponding one of the plurality of thin film filters while reflecting others of the plurality of optical signals back into the first of the plurality of transparent spacers, and reflect the others of the plurality of signals towards a second of the plurality of thin film filters.

Claim (Index 13):
A method for communication, the method comprising:\n in an optical assembly coupled to a top surface of a photonic chip, the optical assembly comprising a lens array on the top surface of the photonic chip, an angled mirror, a plurality of transparent spacers, and a plurality of thin film filters:\n receiving a plurality of optical signals at different wavelengths in the optical assembly from the photonic chip via the lens array; \n reflecting the plurality of optical signals into a first of the transparent spacers using the angled mirror; \n passing at least a first and a second of the plurality of optical signals through a corresponding first and second thin film filter into a second of the transparent spacers; \n passing a third of the plurality of optical signals through the first of the transparent spacers into the second of the transparent spacers without passing through a thin film filter; \n reflecting the second of the plurality of signals onto the first thin film filter via a reflective surface of the first of the plurality of transparent spacers; \n successively reflecting the third of the plurality of optical signal between the reflective surface and the thin film filters until it reflects off of the first thin film filter; and \n coupling the plurality of optical signals into an optical fiber coupled to the optical assembly.
