Silicon-on-nitride waveguides for mid- and near-infrared integrated photonics
نویسندگان
چکیده
Silicon-on-nitride ridge waveguides are demonstrated and characterized at midand near-infrared optical wavelengths. Silicon-on-nitride thin films were achieved by bonding a silicon handling die to a silicon-on-insulator die coated with a low-stress silicon nitride layer. Subsequent removal of the silicon-on-insulator substrate results in a thin film of silicon on a nitride bottom cladding, readily available for waveguide fabrication. At the mid-infrared wavelength of 3.39 lm, the fabricated waveguides have a propagation loss of 5.26 0.6 dB/cm and 5.16 0.6 dB/cm for the transverse-electric and transverse-magnetic modes, respectively.

The standard platform for silicon photonics has been ridge or channel waveguides fabricated on silicon-on-insulator (SOI) wafers. SOI waveguides are so versatile and the technology built around it is so mature and popular that silicon photonics is almost regarded as synonymous with SOI photonics. However, due to several shortcomings of SOI photonics, novel platforms have been recently emerging....
