Abstract
A novel impedance-matched structure is proposed for improved coupling in evanescently coupled, integrated waveguide/photodetectors. We show that insertion of an impedance-matching layer between waveguide and detector regions can improve the coupling by a factor of ≊7, resulting in shorter detectors with lower capacitance and higher frequency response. The impedance-matching mechanism is discussed in detail.Keywords
