Abstract

A VCSEL can include: an elliptical oxide aperture in an oxidized region that is located between an active region and an emission surface, the elliptical aperture having a short radius and a long radius with a radius ratio (short radius) / (long radius) being between 0.6 and 0.8, the VCSEL having a relative intensity noise (RIN) of less than -140 dB / Hz. The VCSEL can include an elliptical emission aperture having the same dimensions of the elliptical oxide aperture. The VCSEL can include an elliptical contact having an elliptical contact aperture therein, the elliptical contact being around the elliptical emission aperture. The elliptical contact can be C-shaped. The VCSEL can include one or more trenches lateral of the oxidized region, the one or more trenches forming an elliptical shape, wherein the oxidized region has an elliptical shape. The one or more trenches can be trapezoidal shaped trenches.

Description

[0001] inventor [0002] Deepa Gazula [0003] Nicola Kittic [0004] Malek Haczynski [0005] gary landry [0006] jim tatum Background technique [0007] Lasers are commonly used in many modern communication components for data transmission. One use that has become more common is the use of lasers in data networks. Lasers are used in many fiber optic communication systems to transmit digital data over networks. In one exemplary configuration, a laser may be modulated by digital data to produce an optical signal comprising periods of light and dark outputs representing a stream of binary data. In actual practice, the laser output represents a high light output that is binary high and a low power light output that represents a binary low. For a fast response time, the laser is always on, but varies from high light output to low light output. [0008] Optical networks have various advantages over other types of networks such as copper wire based networks. For example, ...
