Short pulse generation with 40 GHz passively-mode locked Q-dashed Fabry-Pérot laser [PDF]
, 2009 Generation of sub-picosecond pulses by a DC-biased passively mode-locked Fabry-Perot laser is demonstrated. By using a tunable band-pass filter, it is observed that the width of the generated pulses decreases in direct proportion to the optical modes ...

A nanostructured Fabry-Perot interferometer
Optics Express, 2010 A polymer-based micromachined Fabry-Perot interferometer (µFPI) with embedded nanostructures in its cavity, called nanostructured-FPI, is reported. The nanostructures inside the cavity are a layer of Au-coated nanopores. As a refractive-index sensitive optical sensor, it offers the following advantages over a traditional µFPI for label-free biosensing ...
