Abstract: An integrated circuit is provided with a photonic device and a spot-size converter waveguide device integrated on a common substrate. The spot-size converter waveguide device provides for transformation between a larger spot-size and a smaller spot-size corresponding to the photonic device. The spot-size converter waveguide device includes at least one of a bottom mirror and top mirror, which provide highly-reflective lower and upper cladding, respectively, for vertical confinement of light propagating through the waveguide device. The top mirror overlies opposing sidewalls of the spot-converter waveguide device, which provide highly-reflective sidewall cladding for lateral confinement of light propagating through the waveguide device. Advantageously, the highly-reflective lower cladding provided by the bottom mirror limits optical loss of the waveguide device. Similarly, the highly-reflective upper cladding and sidewall cladding provided by the top mirror limits optical loss of the waveguide device.

Abstract: The surface silicon layer (SOI layer) of an SOI-based optical modulator is processed to exhibit a corrugated surface along the direction of optical signal propagation. The required dielectric layer (i.e., relatively thin “gate oxide”) is formed over the corrugated structure in a manner that preserves the corrugated topology. A second silicon layer, required to form the modulator structure, is then formed over the gate oxide in a manner that follows the corrugated topology, where the overlapping portion of the corrugated SOI layer, gate oxide and second silicon layer defines the active region of the modulator. The utilization of the corrugated active region increases the area over which optical field intensity will overlap with the free carrier modulation region, improving the modulator's efficiency.

Abstract: A microbend-induced fiber grating is formed from a section of optical fiber configured to exhibit “splitting” between the resonant wavelengths supported by the TE and TM components of the LP1m mode and the resonant wavelength supported by the odd/even HE2m components of the LP1m mode. Since only the TE and TM components are polarization dependent, by splitting and shifting the resonant wavelengths for these modes away from a system-desired wavelength(s) supported by the odd/even HE modes, a polarization insensitive microbend-induced fiber grating can be formed. A fiber core configuration including a central core region, trench and ring is formed to exhibit a large radial gradient in core refractive index profile, with a significantly steep transition between the ring index and the trench index, to provide the desired splitting between the (undesired, polarization sensitive) TE/TM modes and the HE mode.
