摘要： A low threshold distributed feedback (DFB) laser is constructed for improved performance at subzero temperatures. A loss grating is employed to enhance the probability that lasing occurs near the short wavelength side of the stopband and to counteract the effect of negative gain tilt that occurs when DFB lasers are positively detuned. A method of making DFB lasers from wafers with improved yield for low temperature side mode suppression ratio (SMSR) is also disclosed.

摘要： Computer system for creating and playing location aware games. The creation process allows for authoring of custom location aware games, training aids, tours and scavenger hunts using a mobile computing device and map. The resulting game can be played using a mobile computing device and location receiver (e.g. GPS receiver).
