Abstract
An optical device that includes 1) a gain section having a plurality of core regions including dopant species configured to absorb incident radiation at a first wavelength and emit radiation at a second wavelength, and 2) at least one passive section attached to the gain section. The gain section and the at least one passive section comprise an optical cavity which selectively promotes in-phase light emission from the optical cavity. An alternative optical device which includes a gain section having a plurality of core regions including dopant species configured to absorb incident radiation at a first wavelength and emit radiation at a second wavelength, and 2) two passive sections attached to the gain section at opposite ends. In this alternative optical device, the gain section and the two passive sections comprise an optical cavity which selectively promotes in-phase light emission from the optical cavity such that the light emission from the optical cavity, in a far field, has a singular Gaussian-like intensity distribution about a longitudinal axis extending from the optical cavity.
