1. Shih, Bing-Hao. Subwavelength grating devices for silicon photonics applications.

Degree: Master, Electro-Optical Engineering, 2016, NSYSU

This thesis focuses on the design and simulation of subwavelength waveguide gratings, which reflect the light at its Bragg wavelength, implemented on silicon-on-insulator (SOI) platform. This photonic device has been utilized as an optical filter, a wavelength division multiplexer, and a sensing element. However, the strong side-lobe ripples arise from the waveguide gratings would cause serious channel crosstalks once the waveguide gratings are used to implement wavelength division multiplexing devices. In this work, we incorporate Gaussian-apodized structure in the waveguide grating design to reduce the side-lobe ripples by means of grating width modulation. Apodized grating is able to obtain a side-lobe suppression ratio of larger than 20 dB. Such an apodization structure is successfully implemented in strip-type and cladding-modulated waveguide gratings for side-lobe suppression. It works for not only uniform gratings but also phase-shifted gratings and sampled gratings. In addition, the moiré grating design, which is composed of two grating periods, is also implemented on SOI waveguides. This moiré grating has a Ï phase shift just like a phase-shifted grating, but more importantly this grating provides a tunable resonant bandwidth, which can not be achieved by a conventional phase-shifted grating. A resonant bandwidth of 0.18, 0.6 and 1.09 nm can be realized by cascading one, two, and three moiré gratings, respectively. Performance variation of the moiré gratings against the fabrication errors is finally investigated.
