Flexible distributed feedback lasers based on nanoimprinted cellulose diacetate with efficient multiple wavelength lasing

Multi-colored polymer lasers Highly luminescent polymers can work as lasers when incorporated with suitable cavities and now the nano-imprinting makes the fabrication much cheaper and more scalable.
