Abstract
A fiber optic device basically comprising an optical fiber/interference filter combination finds useful application in optical communication systems for wavelength selection or bandwidth selection from a multiwavelength light source or emitter. If the emitter is a semiconductor laser, the device may be also employed to provide single longitudinal mode control at the selected wavelength or bandpass.
