Nonvolatile Reconfigurable Phase-Shifted Bragg Grating Filter With Tunable Wavelength and Extinction Ratio
Nonvolatile compact on-chip optical filters with a tunable spectral response are required in low-power optical communication systems and applications. By capping phase change materials (PCMs) films on a phase-shifted Bragg grating (PSBG), the key parameters of a filter such as center wavelength and...
