About this document
Photonic Crystal LEDs: Enhancing Brightness by Chandan Pathak is a document available to read on EtoBox.
The document discusses photonic crystal based LEDs. It explains that photonic crystals can be used to extract light trapped in LEDs, improving their efficiency. The crystals are periodic structures etched into the chip that can diffract light out of horizontally propagating modes. This allows more light to exit the device, increasing brightness without increasing electrical power. Fabricating the photonic crystals presents challenges due to small feature sizes required, but nanoimprint lithography shows pro
