High power surface grating slow-light VCSEL

چکیده
We report on a novel high power vertical cavity surface emitting laser (VCSEL) with order shallow grating, which enables single mode operation even for 6 mm long devices. A of over 3 W is obtained under pulsed operations oxide aperture. fan-shape beam sub-degree narrow divergence up to injection currents 5 A. Thanks the low effective index slow-light modes in VCSEL structure, grating pitch 2.5 μm, can be made by using standard photo-lithography. The simple fabrication process and potentials quality could make proposed good candidate 3D optical sensing imaging applications.

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 کاملLow-Loss Slow Light inside High Contrast Grating Waveguide
We propose a novel hollow-core slow light waveguide using high contrast grating (HCG). Light propagates in air along a path bounded by two HCG layers. A strong interaction between the light and the HCG leads to a large group index, and thus the slow light effect. Waveguide loss and group index can be optimized separately by tuning the HCG and waveguide parameters. High performance slow light is...

A demonstration of a high-power, high-speed 980 nm vertical-cavity surface-emitting laser array with continuous-wave power of greater than 120 mW and frequency response over 7.5 GHz at room temperature is reported. Experimental results show that copper plating the array elements and flip-chip bonding provides effective thermal management as well as offering uniform current distribution at micro...
متن کاملTunable delay slow-light in an active fiber Bragg grating.
We proposed and experimentally demonstrated an extremely simple and feasible slow-light technique to achieve tunable optical delay by using the Er/Yb codoped fiber Bragg grating (FBG). The signal light experiences strong dispersion when it is launched into the reflection edge of FBG, and the group delay value is determined by the signal wavelength and the pump power. In the experiment, a contro...
