Two-Section Gain-Levered Tunable Distributed Feedback Laser with Active Tuning Section
A composite cavity semiconductor laser structure that consists of two active (gain) sections is analyzed. One of the sections has a grating corrugation, while the other is flat. The operation of the device is enhanced by utilizing the gain-lever effect. A round-trip analysis is combined with the rate equations pertinent for this structure to study the characteristics of the device. The performa...
متن کاملTwo-Directional Tuning of Distributed Feedback Film Dye Laser Devices
We demonstrate a two-directional tuning method of distributed feedback (DFB) film dye laser devices to achieve high quality lasing and a large tuning range. In this work, we proposed a simple method to fabricate a continuous tunable solid-state dye laser on a flexible Polydimethylsiloxane (PDMS) film. In order to obtain stable and tunable output lasing, the stretching property of the gelatine h...
متن کاملDistributed feedback-distributed Bragg reflector coupled cavity laser with a Ti:(Fe:)Er:LiNbO3 waveguide.
A thermally fixed photorefractive Bragg grating is written in a single-mode Ti:Fe:Er:LiNbO3 channel waveguide and used to develop a distributed feedback-distributed Bragg reflector coupled cavity laser with a second broadband dielectric cavity mirror. The optically pumped (lambda(p) = 1480 nm, P = 130 mW) laser emits in single-frequency operation as much as 8 mW at lambda = 1557.2 nm with a slo...

متن کاملSingle mode optofluidic distributed feedback dye laser.
Single frequency lasing from organic dye solutions on a monolithic poly(dimethylsiloxane) (PDMS) elastomer chip is demonstrated. The laser cavity consists of a single mode liquid core/PDMS cladding channel waveguide and a phase shifted 15th order distributed feedback (DFB) structure. A 1mM solution of Rhodamine 6G in a methanol and ethylene glycol mixture was used as the gain medium. Using 6 na...
