Article Citation - WoS: 12Citation - Scopus: 12High Transmission Through a 90° Bend in a Polarization-Independent Single-Mode Photonic Crystal Waveguide(The Optical Society, 2015) Erol, Adem Enes; Sözüer, Hüseyin SamiWe propose a polarization-independent single-mode waveguide, using a two-dimensional square photonic crystal with a complete band gap. The waveguide is tuned such that both TE and TM modes have the same group velocity and zero group velocity dispersion at the centergap frequency. We also present results for a 90° bend with transmission values of 98% for both modes.Article Citation - WoS: 97Analysis and Suppression of Nonlinear Frequency Modulation in an Optical Frequency-Domain Reflectometer(The Optical Society, 2009) Yüksel, Kıvılcım; Wuilpart, Marc; Mégret, PatriceA new method for monitoring the nonlinearities perturbing the optical frequency sweep in high speed tunable laser sources is presented. The swept-frequency monitoring system comprises a Mach-Zehnder interferometer and simple signal processing steps. It has been implemented in a coherent optical frequency domain reflectometer which allowed to drastically reduce the effects of nonlinear sweep, resulting to a spatial resolution enhancement of 30 times. © 2009 Optical Society of America.
