Abstract
A laser cavity configuration employs polarization switching to obtain a high output power in a single transverse spatial mode from an integrated external cavity diode laser device. The structure provides stabilization and rapid tuning of the frequency of the diode laser. An advantage is that an integrated structure provides output of the laser in a waveguide with the correct polarization for subsequent applications while supporting optimal polarization in a solid state active medium. The external cavity diode laser according to the invention is consistent with a planar manufacturing process such that high volume, low cost products can be achieved.
