Numerical study of high-index-contrast Er:LiNbO3 photonic wire lasers optically pumped at 980 nm.
For the first time [to our best knowledge] a high-index-contrast z-cut Er:LiNbO(3) photonic wire waveguide laser, optically pumped at 980 nm wavelength, is designed for continuous-wave operation. Waveguide modes and laser characteristics are numerically computed using a developed full vectorial finite-element method based tool. In order to maximize the output power of the laser, the active cavi...
متن کاملDevelopment of 3.6 mW Er- doped C-band super fluorescent fiber source pumped at 980 nm
A 3.6mW single pass backward signal superfluorescent fiber source having a spectral width of 27.417nm was developed at a pump wavelength of 980.5nm and presented the experimental results along with non-flattened ASE spectrum. The fiber source could have direct applications in fiber sensors like fiber gyroscope or, in general, in any optical sensors in which a broad spectral band and high power ...
متن کاملHigh-Power Continuous-Wave Directly-Diode-Pumped Fiber Raman Lasers
We describe novel fiber Raman lasers pumped directly by spectrally combined high power multimode laser diodes at ∼975 nm and emitting at ∼1019 nm. With a commercial multimode graded-index fiber, we reached 20 W of laser output power with a record slope efficiency of 80%. With an in-house double-clad fiber, the beam quality improved to M = 1.9, albeit with lower output power and slope efficiency...
متن کاملSelf-Consistent Modeling of Beam Instabilities in 980-nm Fiber Pump Lasers
Emission nonlinearities such as kinks in the L–I characteristic and beam steering have often been observed in semiconductor power lasers that were designed for single-mode operation. A physical model of these phenomena is presented in which they are attributed to effects of the lasing and coherent coupling of multiple lateral modes. This model has been implemented self-consistently in a finite-...
متن کاملHigh-Speed Datacom VCSELs at 1310 and 980 nm
Recent progress on VCSELs for datacom applications within the author’s group at UCSB will be reviewed. Efforts on ‘all-epitaxial, long-wavelength’ InP-based devices as well as efficient, small-cavity-volume GaAsbased VCSELs will be included. InGaAlAs/InGaAsSb/InP all-epitaxial wafers processed in a conventional manner are found to provide viable VCSELs across the entire 1300-1600 nm wavelength ...
