The output optical power and spectra of a 975 nm semiconductor laser diode (SLD) were measured and analyzed when the SLD was operated with different current in the temperature range of -10°C—65°C. The results showed that the output center wavelength of the SLD shifts in the direction of long wavelength as the operation current and temperature rises. The slopes were approximately 0.24nm/100mA and 0.36nm/°C, respectively. Furthermore, the Conversion efficiency of the SLD was higher when the temperature was low. The reasons for the red shift of SLD was theoretical analyzed.

Proposed the EDFA and EYCDFA power booster (Erbium Doped Fiber Amplifier- Erbium ytterbium co doped fiber amplifier) with quad pumping for high speed and multi wavelength services in an optical communication. The proposed EDFA and EYCDFA power booster with WDM(Wavelength division multiplexing) simulated by dual forward and Backward pumping, Dual-backward pumping, Tri-single forward and dual backward pumping and Quadsingle forward and tri-backward pumping with respect to Pump power and fiber Length. The parameters Input Optical power, Output Optical power, Forward Signal power, Backward Signal power measured and determined the speed of transmission in all types of pumping methods. From that the proposed EDFA- ans EYCDFA power booster with WDM quad pumping is the best suitable for secured high speed optical telecommunication systems. The results shown in Quad pumping Output optical power is maximum 25.2dB and optimum spectral forward Signal power is 30.5dBm and very less spectral optical backward signal power of -25.4dBm with Length 5m

The heterostructure of a quantum-cascade laser based on In0.53Ga0.47As/Al0.48In0.52As heteropair lattice matched with the InP was grown by molecular beam epitaxy. InP layers was used to form the optical waveguide. Room temperature lasing in the spectral range of 8 μm in the standard ridge geometry of a Fabry-Perot cavity formed by cleaved facets with peak output optical power of 0.45 W was obtained.

Abstract In heat-assisted magnetic recording (HAMR), optical power from a laser diode mounted on the slider is used to heat up a nanometer scale area on the disk surface to approximately 450°C, facilitating the writing process. Controlling optical power or current that is applied to the laser diode in HAMR is a critical task. In this study, a fully integrated system of HAMR heads and disks is used to study laser current as a function of the magnetic write width (MWW), the operating radius, and the head-disk clearance. Our experimental results show that the laser current is a linear function of the magnetic write width and the head-disk clearance. As the operating radius increases from the inner diameter to the outer diameter of the disk, the laser current increases by approximately 20%.
