  • Patent number: 8729696
    Abstract: In a testing method for an LD, an LD die is held. Then, electric current increasing with a fixed increment and having a sequence of current values is supplied to the LD die to drive the LD die to emit light and a sequence of voltage values across the LD die and corresponding to the sequence of current values, respectively, is metered. A sequence of power values corresponding to the sequence of current values, respectively, is also metered. Next, an electro-optical property of the LD die is determined according to the sequence of current values, the sequence of voltage values, and the sequence of power values.

  • Patent number: 8679873
    Abstract: The present invention discloses a method for fabricating a heat-resistant, humidity-resistant oxide-confined vertical-cavity surface-emitting laser (VCSEL) by slowing down the oxidizing rate during a VCSEL oxidation process to thereby reduce stress concentration of an oxidation layer and by preventing moisture invasion using a passivation layer disposed on a laser window. The VCSEL device thus fabricated is heat-resistant, humidity-resistant, and highly reliable. In a preferred embodiment, the oxidation process takes place at an oxidizing rate of less than 0.4 ?m/min, and the passivation layer is a SiON passivation layer.

  • Patent number: 8612111
    Abstract: An automatic braking system includes a laser module, an image capturing module, a braking module, and a control module. The laser module emits a laser beam along a forward direction of a vehicle and receives the reflected laser beam. The image capturing module captures a road image in front of the vehicle. The braking module slows the vehicle. The control module is electrically connected to the laser module, the image capturing module, and the braking module. When an intensity of the reflected laser beam is greater than a pre-set value, the image capturing module is controlled by the control module to captures the road image.
