Transforming Fabry-Pérot Resonances into a Tamm Mode

An optical vernier technique for in situ measurement of the length of long Fabry–Pérot cavities

We propose a method for in situ measurement of the length of kilometre-sized Fabry–Pérot cavities in laser gravitational wave detectors. The method is based on the vernier, which occurs naturally when the laser beam incident on the cavity has a sideband. By changing the length of the cavity over several wavelengths we obtain a set of carrier resonances alternating with sideband resonances. From...

Enhanced Modulation Bandwidth of a Fabry–Pérot Semiconductor Laser Subject to Light Injection From Another Fabry–Pérot Laser

Variations in optical spectrum and modulation bandwidth of a modulated Fabry–Pérot (FP) semiconductor laser subject to the external light injection from another FP Laser is investigated in this paper. Optimal wavelength matching conditions for two FP lasers are discussed. A series of experiments show that two FP lasers should have a central wavelength overlapping and a mode spacing difference o...

Fabry–Pérot nanocavities in multilayered plasmonic crystals for enhanced biosensing

We have demonstrated extraordinary light transmission effect through Fabry–Pérot cavities in multilayered plasmonic crystals formed by coupling two physically separated metallic nanohole and nanodisk array layers. Superior field-medium overlap is observed with Fabry–Pérot resonances as a result of stronger electromagnetic field confinement in the dielectric region far from the metallic surfaces...

Electron tunneling into a quantum wire in the Fabry-Pérot regime

Distributed optical fibre sensors based on spontaneous Brillouin scattering employing multimode Fabry-Pérot lasers

Proposed and characterised is the use of multi-longitudinal mode Fabry-Pérot laser sources, in distributed optical fibre sensors based on spontaneous Brillouin scattering, for simultaneous strain and temperature measurements. Experimental results show that, by using such multi-longitudinal mode lasers, it is possible to measure the Brillouin spectrum, even if the overall laser spectral linewidt...
