Latest Patents

One of Ed Vail's latest patents is the "Tunable Controlled Laser Array." This innovative semiconductor laser is capable of emitting light at any of the standard communication wavelengths, which is of great practical value. The design involves fabricating a single semiconductor chip that integrates multiple distributed feedback (DFB) lasers. Each DFB laser is engineered to emit at a different wavelength, allowing for versatile applications. Additionally, a micro-mechanical optical element is included, which controls the output by selecting the appropriate laser stripe. This element can take various forms, such as a sliding waveguide, a movable lens, or a tilting mirror. By fine-tuning the temperature and adjusting the optical element's position, the output wavelength can be precisely set.

Another notable patent is the "Laser and Laser Signal Combiner." This optical communication system is designed to transmit multiple optical beams, each at a different wavelength. It features a laser array with multiple transmitters, each generating distinct optical beams. A diffraction grating is optically coupled to the laser array, ensuring that each beam is diffracted at a uniform angle to create a combined optical beam. This combined beam is then focused into an optical communication medium, enhancing the system's overall efficiency.
