PRINTING OF LIQUID CRYSTAL DROPLET LASER RESONATORS ON A WET POLYMER SOLUTION AND PRODUCT MADE THEREWITH

摘要

A photonic device is manufactured by: (i) providing (e.g. by inkjet printing) an aliquot of a liquid crystal material (504); and (ii) depositing the aliquot onto the surface of a flowable material layer (502) to form a liquid crystal deposit, the flowable material and the LC material being substantially immiscible. The liquid crystal deposit adopts a deformed shape relative to the shape of the aliquot due to interaction with the flowable material layer. This promotes alignment of the LC material. Incorporation of a laser dye allows the photonic device to function as a laser, which can be operated above or below threshold depending on the circumstances. The photonic device can also be used as a passive device based on the photonic bandgap of the aligned LC material.
