Title: The Innovations of David V Lang
Introduction
David V Lang is a notable inventor based in Madison, NJ (US). He has made significant contributions to the field of laser technology, holding a total of 2 patents. His work focuses on enhancing the performance and efficiency of tunable lasers.
Latest Patents
Lang's latest patents include a wavelength tunable laser and a method of formation. This invention discloses a method for increasing the monomolecular recombination and the immunity to noise of a continuously tunable laser. The method achieves a concentration of recombination centers in the range of about 1×10 cm to about 1×10 cm in the tuning region of the laser device. This is accomplished by doping the waveguide layer with impurity atoms, irradiating the waveguide layer with high-energy particles, or varying the growth conditions of the waveguide layer to introduce native point defects due to lattice mismatch. By increasing the monomolecular recombination, the immunity to noise is improved, although the tuning efficiency is slightly reduced. Nevertheless, the overall tuning range remains insignificantly changed over high current ranges. Another significant patent involves a device having a strain-induced region of altered bandgap, which comprises Ge.sub.x Si.sub.1-x layers interleaved with Si layers, making it an excellent photodetector at infrared wavelengths.
