Only long-wavelength VCSELs, having one-tenth the consumption of edge-emitting lasers ... Optical absorption spectroscopy using various laser sources has been demonstrated to be a useful technique ...

Most high-power designs are so-called edge emitters, made from a sandwich ... Welcome to the photonic-crystal surface-emitting laser (PCSEL). Invented by Susumu Noda’s research group at Kyoto ...

They are now widely used for the OLED (organic light-emitting diode) screens found in most mobile phones. A limitation of organic semiconductor lasers is that they typically need another laser to ...

it was demonstrated that photonic crystal surface-emitting semiconductor lasers (PCSELs) can achieve a perfect single mode oscillation in a broad area. By maximizing this advantage, we aim at ...
