Abstract
Efficient fiber to chip couplers are essential for overall efficiency of integrated photonic devices. In this thesis new techniques are developed including using an optimization algorithm for designing adiabatic tapers and thinning of the waveguide over-cladding in the taper region. Several different coupler designs with optimized taper shapes have been fabricated and characterized with losses for some designs reduced below 1 dB.
