Abstract: A mechanically flexible array of optically pumped vertical cavity surface emitting lasers, fabricated using spin coating. The array uses InGaP colloidal quantum dots as an active medium and alternating polymer layers of different refractive indices as Bragg mirrors. Enhanced spontaneous emission is produced. The flexible array can be peeled off a substrate, producing a flexible structure that can conform to a wide variety of shapes, and having an emission spectrum that can be mechanically tuned. The flexible array can be used to create a flexible infrared light bandage.

Abstract: A monolithic wavelength stabilized system comprises a laser monolithically formed with a waveguide splitter having at least two branches. Non-identical resonators having different wavelengths are operatively coupled to each branch of the splitter and a photodiode is communicatively coupled to receive the output from each non-identical resonator. A control unit receives the photocurrent outputs from the photodiodes, determines based on the photocurrents whether the wavelength of the laser signal is at a desired value, and transmits a feedback signal to the laser to move the laser output toward the desired wavelength. The laser, splitter, resonators, and photodiodes are monolithically formed in a single chip using asymmetric waveguides.
