Abstract: A laser for generating deep ultra-violet (DUV) continuous wave (CW) light includes a second-harmonic generator and a fourth-harmonic generator. The fourth-harmonic generator includes a plurality of mirrors as well as first and second non-linear optical (NLO) crystals. The first NLO crystal generates the light having the fourth harmonic wavelength, and is placed in operative relation to the plurality of mirrors. The second NLO crystal is placed in operative relation to the first NLO crystal such that the light having the second harmonic wavelength passes through both the first and the second NLO crystals. Notably, the second optical axes of the second NLO crystal are rotated about a direction of propagation of the light within the second NLO crystal approximately 90 degrees relative to the first optical axes of the first NLO crystal. The second NLO crystal provides no wavelength conversion.

Abstract: An optical device includes first and second waveguides and a micro-ring. The first waveguide is optically coupled to the micro-ring and is separated from the micro-ring by a first gap having a first gap distance. The second waveguide has a supply port, an output port, and a coupling portion optically coupled to the micro-ring. The coupling portion is separated from the micro-ring by a second gap having a second distance. The second gap distance is larger than the first gap distance. The second waveguide and the micro-ring cooperate to form a filter having a stop band. The first gap distance is selected such that a first optical signal on the first waveguide having a first strength causes a first shift in the stop band such that a first wavelength is within the stop band, and wherein the second gap distance is selected such that a second optical signal on the second waveguide having the first strength causes a second or no shift in the stop band such that the first wavelength is outside of the stop band.
