In-plane coupling of light from InP-based photonic crystal band-edge lasers into single-mode waveguides

Hattori, Haroldo; McKerracher, Ian; Jagadish, Chennupati; De La Rue, Richard M; Tan, Hark Hoe


In this paper, we analyze the coupling of light from photonic-crystal band-edge lasers into single-mode waveguides. Both active and passive devices lie in the same plane and coupling of light is achieved by using parabolic and nanotapers in InP based epitaxial structures. Two- and three-dimensional finite-difference time-domain methods are employed to analyze these devices. Coupling efficiencies higher than 80% can be obtained with parabolic couplers. We also present laser configurations that...[Show more]
