Latest Patents

Greg Letal holds a patent for an "Enhanced efficiency laterally-coupled distributed feedback laser." This invention describes a method and apparatus that improves the efficiency of a laterally-coupled distributed feedback (LC-DFB) laser. The design features an effective ridge that provides lateral confinement of guided optical modes through a surface etched grating, which also functions as a DFB element. The invention allows for improved coupling and quantum efficiency by operating in higher order modes, particularly the first order mode, while suppressing other lateral modes through gain-loss discrimination. This technique is particularly beneficial for single-mode LC-DFB lasers that can be monolithically integrated with other elements in photonic circuits.
