High-Order-Mode VCSEL With 12mW Output Power
نویسنده
چکیده
We report high-power single-higher-order transverse mode emission of a large-area oxideconfined rectangular-shaped VCSEL with a multi-spot shallow surface relief. Both a recordhigh output power of 12mW and a record-low differential series resistance of 18 ohms are achieved. Stable single-higher-order transverse mode emission with a side-mode suppression ratio exceeding 35 dB is maintained up to thermal rollover. Measurements of nearand far-field intensity profiles of the higher-order mode are presented.

2 980 nm Photonic Microcavity Vertical Cavity Surface Emitting Laser
Vertical-Cavity Surface-Emitting Laser (VCSEL) is a type of semiconductor laser with laser beam perpendicular to the surface of the semiconductor substrate, as shown in Fig.1(a) [1]. VCSEL has many advantages, such as non-divergence output beam, fabrication and test on wafer, easy two-dimensional integration, and single longitudinal mode work. VCSEL is composed of an active region sandwiched be...

The first error-free data transmission beyond 1 km of multi-mode fiber at bit-rates exceeding 20 Gb/s is demonstrated using a high modulation bandwidth, quasi-single mode (SMSR~20 dB) 850 nm VCSEL. A VCSEL with small ~3 μm aperture shows quasi-single mode operation with a narrow spectral width. The top mirror reflectivity of the VCSEL is optimized for high speed and high output power by shallow...

This paper discusses the design and the internal device physics of novel high-performance vertical-cavity surfaceemitting lasers (VCSELs) emitting at 1.32 μm wavelength. Our VCSEL design features intra-cavity ring contacts, strain-compensated AlGaInAs quantum wells, and an AlInAs/InP tunnel junction. The tunnel junction is laterally confined forming an aperture for current injection and wave gu...

This paper presents an extensive numerical analysis of a high-contrast grating VCSEL emitting at 0.98 μm. Using a three-dimensional, fully vectorial optical model, we investigate the influence of a non-uniform grating with a broad range of geometrical parameters on the modal behavior of the VCSEL. Properly designed and optimized, the high-contrast grating confines the fundamental mode selective...
