The mode frequency tuner is arranged to intercept light oscillating in the resonant optical cavity and is operable to tunably change the mode frequencies of the at least one longitudinal mode of the resonant optical cavity. In another aspect, a resonant optical cavity is provided. The resonant optical cavity supports oscillation of light in at least one longitudinal mode having a respective mode frequency. Light in at least one longitudinal mode in the resonant optical cavity is amplified. The mode frequencies of the resonant optical cavity are changed. The light is transmission band-pass filtered.

In one aspect, a wavelength tunable light source includes a resonant light path, an optical gain medium, an optical grating, a first acousto-optic deflector, and a second acousto-optic deflector. In another aspect, a light source has a resonant light path containing first and second acousto-optic devices for tuning an output light beam over a specified frequency range with an output wavelength profile.

摘要： A spectrum analyzer includes an array of frequency-selective bulk acoustic wave (BAW) resonators each tuned to a predetermined different resonant frequency. The spectrum analyzer further includes a broadband BAW resonator that generates acoustic energy when connected to a signal source. An acoustic coupling transmits the acoustic energy generated by the broadband BAW resonator to the frequency-selective BAW resonators so that one of the frequency-selective BAW resonators will generate an electrical output signal if the acoustic energy transmitted from the broadband BAW resonator contains spectral components at its predetermined resonant frequency.

摘要： An apparatus for optically shifting the frequency of an input signal beam includes a first Raman medium that receives an input signal beam, a first pump beam, and a first reference beam to responsively generate an intermediate signal beam comprising a Raman sideband of the first Raman medium. A second Raman medium is optically coupled in series with the first Raman medium. The second Raman medium receives the intermediate signal beam, a second pump beam, and a second reference beam to responsively generate an output signal beam comprising a Raman sideband of the second Raman medium. The generated output signal represents the input signal that is shifted in frequency by a frequency shift that corresponds to the frequency difference between the first and second reference beams.
