Nanoimprinted Organic Semiconductor Laser Pumped by a Light-Emitting Diode
MetadataShow full item record
An organic semiconductor laser, simply fabricated by UV-nanoimprint lithography (UV-NIL), that is pumped with a pulsed InGaN LED is demonstrated. Molecular weight optimization of the polymer gain medium on a nanoimprinted polymer distributed feedback resonator enables the lowest reported UV-NIL laser threshold density of 770 W cm(-2), establishing the potential for scalable organic laser fabrication compatible with mass-produced LEDs.
