1. Development of 1.3-μm GaAs-based vertical-cavity surface-emitting lasers
Abstract : Long-wavelength vertical-cavity surface-emitting lasers (VCSELs) are desirable as low-cost sources for optical metropolitan-area and access networks. In the development of 1.3-µm VCSELs, most attention today is given to monolithic GaAs-based solutions, although no established active material exists in this wavelength region. READ MORE

3. Epitaxial growth optimization for 1.3-um InGaAs/GaAs Vertical-Cavity Surface-Emitting lasers
Abstract : Long-wavelength (1.3-μm) vertical-cavity surface-emitting lasers (VCSELs) are of great interest as low-cost, high performance light sources for fiber-optic metro and access networks. During recent years the main development effort in this field has been directed towards all epitaxial GaAs-based structures by employing novel active materials. READ MORE

4. Photoluminescence Studies of Polytype Heterostructured InP Nanostructures
Abstract : The interface between two semiconductors significantly influences their optical and electronic properties. In contrast to traditional material heterostructures, polytype heterostructures between wurtzite (wz) and zincblende (zb) segments in homomaterial InP nanostructures exhibit sharp interfaces with minimal strain.
