  • Distributed Feedback Semiconductor Lasers
    Distributed Feedback Semiconductor Lasers. This text covers the materials, operation and design strategies of DFB lasers. It provides detailed accounts of large-signal time-domain numerical modeling techniques, which can be extended to optical systems and components other than DFB lasers.
  • Advantages of Semiconductor Laser Diodes Versus Helium Neon Gas Lasers
    Although HeNe gas lasers offer exceptional reliability and optical quality, users are quickly replacing them in their OEM applications with semiconductor laser diode technology. Laser diode modules offer many physical and electronic advantages over HeNe lasers. HeNe gas lasers provide superior
  • The Principles of Semiconductor Laser Diodes and Amplifiers: Analysis and Transmission Line Laser Modeling
    The Principles of Semiconductor Laser Diodes and Amplifiers: Analysis and Transmission Line Laser Modeling. Focusing on the principle applications of SLAs, this book illustrates the growing importance of these functional components in the future of optical communications systems.
  • Correction Methods for Semiconductor Laser Diodes
    A laser diode naturally produces a beam that is divergent, elliptical, and astigmatic. A variety of optical procedures are available to correct for these deficiencies, procedures that enable a laser diode module to produce a circular, diffraction-limited beam with very low divergence. * We can
  • Single-mode Semiconductor Reference Oscillator Development for Coherent Detection Optical Remote Sensing Applications
    High power single mode, tunable, narrow linewidth semiconductor lasers in the 2.05-µm wavelength region are needed for coherent detection optical remote sensing applications. 2.05-µm Fabry Perot (FP) and distributed feedback (DFB) ridge waveguide lasers fabricated from epitaxially grown InGaAsSb
  • Semiconductor Inspection
    There are a number of techniques that are utilised today in the post process on line optical inspection of semiconductor wafers. These include: * Spectroscopic reflectometry where multiple laser wavelengths are shone down onto the surface of the thick film covered substrate to obtain information
  • Semiconductor Manufacturing Processes and Laser Displacement Sensors (.pdf)
    One of the driving forces in the semiconductor manufacturing industry today is to reduce manufacturing cost and increase efficiency. In the past, laser displacement sensors have been used infrequently due to lack of speed, accuracy and flexibility. Recently, laser displacement sensors have become
  • Optical Feedback in Photodigm's Laser Diodes - Application Note
    External feedback effects to semiconductor lasers of all varieties has been well studied [1]-[3]. These feedback effects impact all semiconductor lasers equally from Fabry-Perot (FP) lasers to. distributed feedback (DFB) lasers to distributed Bragg reflector (DBR) lasers.
