Combining Different in-Plane Photonic Wire Lasers and Coupling the Resulting Field Into a Single-Mode Waveguide

Abstract

Abstract-Photonic wire lasers are compact light sources that are fabricated in high-index contrast waveguides (with typical widths of a few hundreds of nanometers). Because of their small footprints, they may become a basic laser component in future-generation of optical integrated circuits. Owing to having low optical volume by design, photonic wire lasers can only produce low output power that may not be adequate in many applications. A solution to this problem is to coherently combine the output power of different photonic wire lasers to produce larger output power. In this article, we analyze different ways to combine light coming out from photonic wire lasers and couple the combined power into a single-mode waveguide.

Calculating intersubband transition energy in T-shaped quantum wire using FD technique

“…Semiconductor nanostructure has become the topic of research in last few years because of the possibility of making novel electronic [1][2] and photonic devices [3][4] by virtue of rapid advancement of existing microelectronics technology [5][6]. Quantum confinement is achieved because dimension of the structures are less than or comparable to de-Broglie wavelength, which results in quantization of energy levels along one, two or three dimensions, realized as quantum well, wire and dot.…”
