    Abstract: The development and encroachment of high technology, from transportation, computation to information is based on the availability of materials in the form of single crystals. With progress in crystal growth technology and characterization, organic, inorganic, semiorganic and organometallic materials having attractive nonlinear optical (NLO) propert... Show More

    Abstract: In this paper, we investigate conditions to form whispering gallery modes (WGMs) in small nanocavities (NCs) which are designed at the intersection area of couple of nanobeams (NBs) structures. Tapered air-holes at each branch of NBs have been employed as a part of mirror accompanied by curved-walls at cross junctions to form a small curved nanocav... Show More

    Abstract: OLEDs are solid-state devices composed of thin films of organic molecules that create light with the application of electricity. OLEDs can provide brighter, crisper displays on electronic devices and use less power than conventional light-emitting diodes (LEDs) or liquid crystal displays (LCDs) used today. OLEDs are made by placing thin films of or... Show More

    Abstract: In this paper, a 1310nm intracavity structure Vertical Cavity Surface Emitting Laser (VCSEL) has been designed using quaternary compound material of AlGaInAs in both QW and barrier but with different composition. This choice has been made instead of choosing widely used GaInAsP/ InP, GaInAsN/ GaAs to gain some advantages. This combination has shown... Show More
