Masters Project Integrated Optical Microsystems Group (IOMS) Design and Optical Characterization of Rare Earth Doped On-chip Waveguide
 

Summary: Masters Project Integrated Optical Microsystems Group (IOMS)
Design and Optical Characterization of Rare Earth Doped On-chip Waveguide
Laser Components
Introduction
Active micro and nano-photonic devices are considered critical wherever their integration
with other functional nano-structures on the same chip is required, e.g. in optical
communication and portable, airborne or space equipment. Amorphous oxide materials doped
with rare earth elements, in particular Er:Al2O3, are potentially very useful for such
applications. For practical realization in integrated circuits the light is confined in two
directions by realizing a channel waveguide structure, which can then be used to guide the
light and perform multiple functions on-chip.

Project Description
An important part of the project will be characterization of channel waveguide devices
such as splitters and couplers, and on-chip resonator structures, such as ring resonators and
reflection gratings (see Fig. 1). Basic characterization of the loss and gain figures of these
devices will be critical for the optimization of the design of the amplifiers and lasers. The
specific tasks of the student will be to carry out characterization of optical test structures and
