The existence of amplified spontaneous emission (ASE) is a fundamental principle of laser dyes. ASE indicates the spectral variation of the optical gain of a laser dye. Analyzing the spectral distribution of ASE is important for designing lasers. We

We present SU-8 polymer waveguide grating couplers for TE mode with enhanced refractive index contrast by employing air as upper and lower cladding layer. Numerical simulations predict a coupling loss of 4.9 dB, indicating a coupling efficiency of 32

The authors present a loss engineering method for slow-light photonic crystal (PhC) waveguides. Our proposed method for engineering the loss is based on optofluidic techniques to produce low propagation loss in the low dispersions slow-light regime.
