We demonstrate a high-power blue diode laser operated at 447 nm combining laser diodes using an optical fiber bundle. As many as 127 diode lasers at 447 nm were
We demonstrate a broad area(400 μm) high power quantum cascade laser(QCL). A total peak power of 62 W operating at room temperature is achieved at λ~ 4.7 μm.
As technology node shrinks, aggressive design rules for contact and other back end of line(BEOL)layers continue to drive the need for more effective full chip p
In the paper, the influences of the chip, silicone and phosphors on the color coordinate shift of LED were studied. In the process of LED baking, it was found t
