The effect of mesa size on the thermal characteristics of etched mesa vertical-cavity surfaceemitting lasers(VCSELs) is studied. The numerical results show that
Patterned porous silicon (PS) films were synthesised by using hydrogen ion implantation technique and typical electrochemical anodic etching method. The surface
The organic π-conjugated polymers are of major interest materials for the use in electro-optical and nonlinear optical devices. In this work, for a selected po
