We propose a new approach for the design of a cavity for atom vapor based devices, where atomic manipulation via two frequencies is required. The cavity provides a homogenous field at two different frequency bands -6.8 GHz and 2 MHz; the first frequency is supported by a cylindrical resonator with conductive walls and dielectric bases, the second frequency is applied from an external source and penetrates...
We present experimental results demonstrating enhanced current modulation of an antireflection-coated edge-emitting laser diode placed in an external cavity. By eliminating the internal cavity of the laser diode and matching the external cavity free spectral range to the modulation frequency we have increased the modulation response up to nearly complete carrier suppression. We demonstrate the tunability...
