Realization of spectrally engineered semiconductor Fabry-Perot lasers with narrow geometrical tolerances
Spectrally engineered semiconductor Fabry-Perot laser resonators are designed to enhance the optical feedback for selected longitudinal modes, which thereby require less gain for lasing. This is achieved by introducing refractive index perturbations along the length of the resonator. However, the physical realization of these resonators is a challenge because of very narrow tolerances; in parti...
متن کاملWDM-PON based on wavelength locked Fabry-Perot lasers
We demonstrate 4-channel WDM-PON with 50 GHz channel spacing based on wavelength locked F-P LDs. The transmission bit rate and the length between the CO and the subscriber is 155 Mb/s and 20 km, respectively. The proposed WDM-PON can accommodate 80 channels with EDFA based broadband light source.
متن کاملHigh-accuracy Fabry–Perot displacement interferometry using fiber lasers
We describe ongoing work in a Fabry–Perot interferometry system designed to measure displacements over a range of 50 mm with sub-pm uncertainty. The apparatus involves probing two nearby modes of the Fabry–Perot cavity with narrow-linewidth fiber telecom lasers and measuring both the mode spacing and the absolute mode frequencies relative to a third, frequency-stabilized, fiber laser. We explor...
متن کاملTeaching Physics with 670-nm Diode Lasers -- Experiments with Fabry-perot Cavities
In a previous paper we described details of the construction of stabilized 670-nm diode lasers for use in undergraduate physics laboratories. We report here a series of experiments that can be performed using the 670-nm diode laser, a homemade scanning Fabry-Perot cavity, a helium-neon laser, a simple photodiode, and a few pieces of electronics hardware. The experiments include: 1) an introduct...
متن کاملHolographic Fabry-Perot spectrometer.
We propose a spectrum analyzer based on the properties of a hologram recorded with the field transmitted by a Fabry-Perot etalon. The spectral response of this holographic Fabry-Perot spectrometer (HFPS) is analytically investigated in the paraxial approximation and compared with a conventional Fabry-Perot etalon of similar characteristics. We demonstrate that the resolving power is twice incre...
