An organic dye-doped polymer laser with a novel wavelength-tuning mechanism is proposed. This device is a vertical cavity surface-emitting laser realized by using a couple of distributed Bragg reflectors (DBRs), on which a dye-doped polymer thin film and a polydimethylsiloxane film are deposited individually. One of the DBRs is electrically driven to vary the effective cavity length. Under the optical excitation, tunable lasing operation with high stability can be achieved when immersion oil is used for the refractive index matching in the cavity. Since the device operation mechanism proposed here is quite simple, it is promising for designing a compact laser device with wide, precise, and electrically driven wavelength tunability.
