Title Micro-transfer printing for visible light communications applications / Katherine Jeanne Rae.
Name Rae, Katherine Jeanne. .
Abstract The work presented in this thesis focuses on the transfer printing of InGaN-based blue emitting light emitting diodes (LEDs) onto various non-native substrates for visible light communications applications. The controlled mechanical integration of photonic structures onto non-native substrates using micro-transfer printing (µTP) techniquesis paving the way to high-performance, heterogeneous and multi-functional integrated photonic devices.
Abstract 2µm-thick 100µm x 100µm LEDs are transfer printed onto these non-native, capability enhancing, substrates using a modified nano-lithography system. Blue-emitting µLEDs in this thin, transfer printable format, were integrated into an array of green-emitting µLEDs to create a dual-colour µLED on a single chip. This chip is then electrically andoptically characterised and demonstrated to examine its potential for data communications applications. The same blue-emitting µLEDs are also integrated with colloidal quantum dot (CQD) colour-converting structures. This yields integrated red, green and orange colour-converting structures all pumped by the blue-emitting transfer printed µLEDs. The µTP technique is finally used to fabricate an integrated optical transceiver device.
