Abstract : Physical Optics Corporation (POC) proposed a new concept of creating photonic band gaps on optical waveguides for the realization of low loss bands. These low loss bands are particularly useful for the realization of high density optical interconnection networks for multi-chip modules and other single-board high-speed functional circuits. In the Phase I program, POC focused on the structures that can be used to construct waveguide photonic band gap structures, namely 2-D and I-D PBG structures. The understanding of these structures and a theoretical study of their contributions to optical beam confinement have been achieved. We further examined their operational properties, including polarization dependence and material index differential requirements. Beam confinement conditions for a large range of off-axis beam angles have been identified between two 1-D PBG structures, which is the basis for the construction of low loss waveguide bands. This strong beam confinement for large angle off-axis beams is not achievable in conventional optical waveguides based on total internal reflection. The applications of the waveguide PBG structures include high density optical interconnect buses, waveguide filters, micro-ring tunable filters and lasers, switches, and integrated wavelength division multipliexers.
