By Yue Wang

This thesis specializes in parts - the advance of miniature plastic lasers that may be powered by way of LEDs, and the appliance of those lasers as hugely delicate sensors for vapours of nitroaromatic explosives (e.g. TNT). Polymer lasers are tremendous compact noticeable lasers; the examine defined within the thesis is groundbreaking, riding ahead the know-how and actual knowing to permit those lasers to be repeatedly pumped by way of a unmarried high-power LED. A striking strengthen within the paintings is the demonstration of nanoimprinted polymer lasers, which show the world's lowest pump threshold densities by way of orders of significance. The thesis additionally advances the appliance of those compact, novel lasers as hugely delicate detectors of explosive vapours, demonstrating that swift detection should be accomplished whilst microporous polymers are used. This paintings additionally demonstrates a prototype CMOS-based microsystem sensor for explosive vapours, exploiting a brand new detection approach.
