| To form the emitter (right), the researchers bond their infrared micro-cavity (center) directly on to the pumping laser diode (left). Manufactured in a three step process, the team feels that its sensor suits low-cost mass production - an essential requirement for the automotive sector. A four inch germanium wafer would provide around 10 000 emitters. (credit: IMPECC) |
