abstract

We experimentally demonstrate transmission characteristics of a W1 photonic crystal waveguide in silicon on sapphire at mid infrared wavelength of 3.43 m. Devices are studied as a function of lattice constant to tune the photonic stop band across the single wavelength of the source laser. The shift in the transmission profile as a function of temperature and refractive index is experimentally demonstrated. In addition to zero transmission in the stop gap, high transmission was observe for the characteristic of the waveguiding behavior of photonic crystal line defect modes. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
