A seminal paper about examples of these devices with multiple quantum wells was published by Nakamura et al., who used indium gallium nitride as a substrate.
An important parameter for these devices is their slope ef᥸ciency. A buried heterostructure implements a stripe geometry surrounded by a lower refractive index to form an index-guided example of this device. Stabilizing the temperature of these devices is important in order to avoid sudden jumps in their mode spectrum. A seminal paper about examples of these devices with multiple quantum wells was published by Nakamura et al., who used indium gallium nitride as a substrate. The VCSEL (VIK-sel) type of these devices is made with a distributed Bragg re᥸ector to cap the cavity. The output of these devices, which is manipulated to make it collimated, depends on the bandgap of the optical gain medium. For 10 points, name these semiconductor devices that create beams of light via stimulated emission.
