Frequency Stabilization of a Waveguide Laser Using Pound-Drever-Hall
Abstract
The generation of ultra-stable model-locked pulses in the 1550 regime is required for high resolution signal processing applications that include electro-optic sampling, transient probes, and optical clocks. More recently the frequency combs comprising these pulses have been applied to innovative methods of Arbitrary Waveform Generation (AWG) in the optical domain. Temporal stability in certain of these applications assumes the utmost importance. A proven approach to address the key issue, entails a significant reduction in system dimensions by means of an Erbium-Doped Waveguide Amplifier (EDWA), which can minimize adverse effects of thermal gradients. To further enhance the long term stability, a Pound-Drever-Hall (PDH) technique can be used to lock the laser to a known frequency reference, in effect allowing the cavity to compensate for the laser's drift. We report for the first time to our knowledge the result of incorporating PDH stabilization in an Erbium-Doped Waveguide Laser (EDWL), and compare this with a commercially available Erbium Doped Fiber Laser (EDFL)
