Semiconductor lasers with a 10 μm wide lateral waveguide of a mesa-stripe design were developed and their light characteristics were studied. Lasers with a 4.6mm long cavity is shown to have a continuous wave (CW) optical power of 2.6W at a heatsink temperature of 25◦C. Lasers with a shorter cavity (< 3mm) showed a lower value of the maximum optical power due to a thermal rollover of the light-current curve.

Mesa Stripe

At ultrahigh levels of pulsed current pumping, the characteristics of semiconductor lasers based on an asymmetric heterostructure with a broadened lateral waveguide of a mesa-stripe design are studied. A peak power of 5.1 W is demonstrated at a pump current amplitude of 10 A. Three types of spatial dynamics of laser radiation are determined: the first one is a slow (~ 200 ns) intensity profile variation along the lateral near field at initial level of pump currents; the second one is a presence of fast (~ 10 ns) processes of mode competition at moderate pump currents; the third one is a chaotic temporal behavior of the output power at maximum pump currents.

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.
