Latest Patents
Raymond's latest patents include groundbreaking inventions such as the "Multi-band multiwavelength quantum dot mode-locked lasers." This invention provides a multi-band (multi-color) multiwavelength mode-locked laser diode through dynamic phase compensation of a quantum dot active medium. The laser diode features a PIN diode structure, where the active medium consists of multiple layers of quantum dots produced by self-assembly from known chemical beam epitaxy methods. The invention allows for the production of multiple bands through AC Stark splitting, frequency selective attenuation, or by including different layers with respective peak ASE emissions. Additionally, dispersion compensation within laser facets, waveguides, and optically active media enables the selection of a fixed dispersion within the cavity. A dynamic group phase change induced by the AC Stark effect allows for sufficient compensation of the fixed dispersion to produce an intraband mode-locked laser, with even interband mode locking observed.
Another notable patent is the "Quantum dot based semiconductor waveguide devices." This invention provides methods and devices for a multiwavelength laser suitable for multicasting and other optical communications applications. The quantum dot-based multiwavelength laser features a monolithic gain block with both upper and lower InP cladding layers. The system includes a middle quantum dot layer with multiple stacked layers of InAs quantum dots embedded in InGaAsP. When supplied with a continuous wave injection current, the laser system produces an output spectrum with equally spaced multiple emission peaks. Furthermore, when an input optical data signal is applied, the laser system duplicates the data across multiple different wavelengths.
