Abstract: A light-emitting device includes a light-emitting diode having an emissive surface, and a capping layer including an organic solid crystal overlying the emissive surface. The refractive index of the organic solid crystal may be tuned such as through the application of a voltage, current, or stress to improve the light extraction efficiency of the device.

Abstract: A MEMS-based vertical cavity surface emitting laser (VCSEL) includes an embedded photodiode. A representative VCSEL includes a distributed Bragg reflector (DBR), a photodiode structure located within the distributed Bragg reflector, an active region overlying the distributed Bragg reflector, and a MEMS upper reflector disposed over the active region. The VCSEL may be configured as an optical sensor. The laser cavity and hence a working wavelength of the sensor may be tuned by modulating the MEMS reflector such as through an applied voltage.
