1550 nm high contrast grating VCSEL.
We demonstrate an electrically pumped high contrast grating (HCG) VCSEL operating at 1550 nm incorporating a proton implant-defined aperture. Output powers of >1 mW are obtained at room temperature under continuous wave operation. Devices operate continuous wave at temperatures exceeding 60 degrees C. The novel device design, which is grown in a single epitaxy step, may enable lower cost long w...

متن کاملHeterogeneously integrated long-wavelength VCSEL using silicon high contrast grating on an SOI substrate.
We report an electrically pumped hybrid cavity AlGaInAs-silicon long-wavelength VCSEL using a high contrast grating (HCG) reflector on a silicon-on-insulator (SOI) substrate. The VCSEL operates at silicon transparent wavelengths ~1.57 μm with >1 mW CW power outcoupled from the semiconductor DBR, and single-mode operation up to 65 °C. The thermal resistance of our device is measured to be 1.46 K...
متن کاملSubwavelength metal grating metamaterial for polarization-selective optical antireflection coating
A metamaterial structure consisting of a one-dimensional metal/air-gap subwavelength grating is investigated for optical antireflection for a germanium surface in the infrared regime. For incident light polarized perpendicularly to the metal grating lines, the metamaterial exhibits effective dielectric properties, and the Fabry–Perot-like resonance results in the elimination of the reflection a...
متن کاملTheoretical analysis of subwavelength high contrast grating reflectors.
A simple analytic analysis of the ultra-high reflectivity feature of subwavelength dielectric gratings is developed. The phenomenon of ultra high reflectivity is explained to be a destructive interference effect between the two grating modes. Based on this phenomenon, a design algorithm for broadband grating mirrors is suggested.
