Integration of active and passive photonic crystal based optoelectronic components

摘要

Two examples of integrating active and passive photonic crystal devices are discussed. A first example integrates two tunable laser diodes with a passive photonic crystal Y-coupler structure. The tunable laser diode is defined by two photonic crystal channel waveguides that are coupled longitudinally through photonic crystal coupling sections. The waveguides have slightly different lengths and hence exhibit slightly different longitudinal mode spacings. The front and rear reflectors are realized by photonic crystal mirrors with lattice dimensions chosen to achieve the desirable mirror reflectivities. Secondly, a passive superprism structure is discussed that can be integrated with an array of photo diodes to build highly integrated receivers for optical networks.
