Latest Patents
Derek's latest patents include a tunable blue laser diode and periodic electric field poled crystal waveguides. The tunable blue laser diode is a harmonic generator laser system that features a distributed Bragg reflector (DBR) or distributed feedback (DFB) tunable diode laser. This innovative system is coupled to a quasi-phase matched (QPM) waveguide made of optically nonlinear material. The tuning of the DBR laser can be achieved thermally or via current injection, allowing for precise control over the wavelength. This technology enables the halving of the wavelength of a red laser into the visible blue spectral band. Additionally, the periodic electric field poled crystal waveguides involve several embodiments for induced electric field poling of QPM nonlinear crystal materials, such as LiNbO.sub.3, LiTaO.sub.3, and KTP. This method avoids the need for conductive electrodes, simplifying the poling process.
