Paper Abstract

This paper describes work to develop a new class of micro- photonic components for use in future opto-electronic circuits. Recent advances aimed at creating practical devices include achieving continuous room-temperature operation in optically and electrically driven microdisk lasers. The improved performance is realized by the simultaneous optimization of thermal, optical, and electrical design. A novel post-processing technique to precisely control the lasing wavelength of optically pumped microdisk lasers will be discussed. Using this technique, the lasing wavelength can be tuned by more than 8 nm. Dependence of the wavelength shift on the radius of the microdisk lasers will be addressed. The ultimate performance of micro-photonic components is constrained by the physics governing device operation. As these micro-photonic devices approach the nanometer scale, quantum effects become important placing new constraints to practical device design. Noise characteristics of scaled devices with very small numbers of photons and carriers need to be understood.
