A multiwavelength erbium-doped fiber laser stabilized by four-wave mixing in a silicon waveguide was investigated. The laser produced five output wavelengths with 0.38 nm spacing at room temperature.
Theoretical and experimental results of mid-infrared (mid-IR) gratings for coupling between transverse-electric (TE)/transverse-magnetic (TM) mode silicon-on-sapphire (SOS) waveguides and zirconium, barium, lanthanum, aluminum, and sodium fluoride (ZBLAN) fibers are presented. The shallow-etched uniform grating, full-etched subwavelength grating, and apodized grating are analyzed theoretically. TE...
