Abstract

An ultra‐short‐wavelength filter using photonic band gap (PBG) mode‐related dispersion in a two‐moded waveguide is proposed. It is verified using the finite‐difference time‐domain (FDTD) method, such that two channels on the PBG edges are affected by opposite dispersive effects and can be separated by an ultra‐short coupler length much shorter than the required length without the assistance of PBG dispersion. © 2005 Wiley Periodicals, Inc.

In this investigation, we propose and demonstrate experimentally tunable and stable dual-wavelength erbium doped fiber (EDF) double-ring laser scheme using different coupling losses inside cavity loop for wavelength and mode spacing tuning. Besides, a shorter unpumped EDF is also used to filter the
