Abstract: A method and system for coupling optical signals into silicon optoelectronic chips are disclosed and may include coupling one or more optical signals into a back surface of a CMOS photonic chip in a photonic transceiver, wherein photonic, electronic, or optoelectronic devices may be integrated in a front surface of the CMOS photonic chip. Optical couplers, such as grating couplers, may receive the optical signals in the front surface of the chip. The optical signals may be coupled into the back surface of the chips via optical fibers and/or optical source assemblies. The optical signals may be coupled to the optical couplers via a light path etched in the chips, which may be refilled with silicon dioxide. The chips may be flip-chip bonded to a packaging substrate. Optical signals may be reflected back to the optical couplers via metal reflectors, which may be integrated in dielectric layers on the chips.

Abstract: Methods and systems for stabilized directional couplers are disclosed and may include a system comprising first and second directional couplers formed by first and second waveguides, where one of the waveguides may comprise a length extender between the directional couplers. The directional couplers may be formed by reduced spacing between the waveguides on opposite sides of the length extender. An input optical signal may be communicated into one of the waveguides, where at least a portion of the input optical signal may be coupled between the waveguides in the first directional coupler and at least a portion of the coupled optical signal may be coupled between the waveguides in the second directional coupler. Optical signals may be communicated out of the system with magnitudes at a desired percentage of the input optical signal. The length extender may add phase delay for signals in one of the first and second waveguides.
