Abstract
The present invention concerns a design for an external cavity single mode laser wherein a short optical path length for the optical cavity (e.g., ˜3 to 25 mm) provides sufficient spacing of the longitudinal modes allowing a single wavelength selective element, such as a microfabricated etalon, to provide a single mode of operation, and optionally a selectable mode of operation.
