Abstract

Silicon-photonic devices are tuned by selective photo removal of chalcogenide glass upper claddings. Phase delays in Mach-Zehnder interferometers and coupling ratios of ring resonators are adjusted. The transfer functions of devices remain stable following trimming.

Abstract

The rapid post-fabrication trimming of the group index in hybrid chalcogenide-on-silicon Mach-Zehnder interferometers is demonstrated. Index changes of 0.065 are achieved through photo-induced mass transfer in an As10Se90 layer.

Abstract

A hybrid Mach-Zehnder interferometer with directly bonded LiNbO3 on silicon-on-insulator waveguides is designed and demonstrated. The transfer function of the device shows a pi phase shift subject to an external field of 0.5 V/micro-meter

Abstract

Silicon photonic devices are tuned by selective photo removal of upper chalcogenide glass layers. Phase delays in cascaded interferometer filters and couplers of ring resonators are arbitrarily adjusted. Responses remain stable following trimming.
