Semiconductor Today features "Semi-polar indium gallium nitride laser diode/waveguide photodiode combo"
"Researchers based in Saudi Arabia and USA have integrated a waveguide photodetector (WPD) with a 405nm laser diode (LD) using free-standing semi-polar gallium nitride (GaN) technology." http://www.semiconductor-today.com/news_items/2017/mar/kaust_240317.shtml
About
"Researchers based in Saudi Arabia and USA have integrated a waveguide photodetector (WPD) with a 405nm laser diode (LD) using free-standing semi-polar gallium nitride (GaN) technology."
"The team comments: “The increased cutoff frequency of the WPD is associated with the reduced device size owing to the narrow ridge design and the improved responsivity of the semi-polar plane WPDs. The high-speed WPD suggests its potential as an integrated receiver for on-chip communication and VLC applications.”
