Analysis of Self-Collimation Based Cavity Resonator Formed by Photonic Crystal

By Natesan Yogesh and Venkatachalam Subramanian
Progress In Electromagnetics Research M, Vol. 12, 115-130, 2010


The self-collimation effect in photonic crystal is used for the realization of open cavity resonator formed by photonic prisms in a four-port arrangement. The confinement, field enhancement and energy storage capabilities of the proposed cavity are explored in this paper. The effect of dielectric losses included in the system and role of the position of line source in the confinement effect of the cavity are brought out. Decay of short Gaussian pulse placed inside the cavity is analyzed through finite-difference time-domain studies. Due to the high confinement and divergence less beam propagation, utility of the proposed cavity for rotational gyroscope application is also revealed.
