摘要： A first stack of distributed Bragg mirrors having alternating layers of aluminum gallium arsenide differing in concentrations of an aluminum are disposed on a surface of a substrate with a first plurality of continuous gradient layers positioned between the alternating layers of differing aluminum concentrations to dynamically move the aluminum concentration from one of the alternating layer to another alternating layers. A first cladding region is disposed on the first stack of distributed Bragg mirrors. An active region is disposed on the first cladding region with a second cladding region being dispose on the active region. A second stack of distributed Bragg mirrors having alternating layers of aluminum gallium arsenide differing concentrations of aluminum are disposed on the second cladding region with a second plurality of continuous gradient layers being positioned between the alternating layers of differing aluminum concentrations to dynamically change the aluminum concentration from one of the altering layers to another alternating layers.

摘要： A high efficiency vertical cavity surface emitting laser with first and second mirror stacks and an active area sandwiched therebetween. The second mirror stack is formed into a mesa with exposed end surface and outer sidewalls and a centrally located light emission region. A portion of the mesa adjacent the exposed outer sidewalls has a reduced electrical conductance so as to spread operating current from the outer sidewalls into the centrally located light emission region. The electrical conductance of the portion is reduced by oxidizing or etching the outer sidewalls.

摘要： A VCSEL (113) having a first and a second stack of distributed Bragg reflectors (120, 116) and an active region (118) defining a light generating and emitting path. A layer (104) of semiconductor material is formed on the second stack (116) so as to intersect the light path and a first electrode (106) and a second electrode (108) are disposed on the layer (104) to form a metal-semiconductor-metal photodetector (102).

摘要： A vertical cavity surface emitting laser (VCSEL) having a first and a second mirror stack and an active region is formed utilizing epitaxial layer growth techniques. A lateral photodetector is integrally formed in the epitaxial growth layers, thereby providing for a VCSEL with laterally integrated photodetector. An isolation region is formed in the epitaxial growth layers between the VCSEL and the photodetector thereby isolating the VCSEL and the lateral photodetector. The integrated VCSEL and lateral photodetector capable of monitoring reflected laser emission, thus laser power output of the VCSEL and employing feedback to maintain a specific laser power output level, thereby capable of automatic power control (APC).
