ADVANCES M SILICON PERIODIC MICROSTRUCTURES WITH PHOTONIC BAND GAPS IN THE NEAR INFRARED REGION

摘要

In this work we present experimental and numerical results relative to reflectivity spectra of micromachined one-dimensional photonic crystals (1D-PhCs), evaluated in the near infrared region at normal incidence with an improved experimental setup, based on single-mode optical fibers with lensed terminations. A Gaussian stochastic process was exploited in the numerical calculation to evaluate the effects of fabrication-induced non-idealities of the devices and limitation of the optical setup, on the reflectivity spectra.
