摘要： In a method of amplifying optical input signals over a wide bandwidth, the optical input signals are applied to an optical waveguide made from a rare-earth-doped amorphous material (e.g., erbium-doped SrY4(SiO4)3O material). The optical input signals include optical signals having wavelengths over a range of approximately 125 nanometers. Pump light is applied to the optical waveguide to cause the waveguide to provide optical gain to the optical input signals. The optical gain causes the optical signals to be amplified within the waveguide to provide amplified optical signals over approximately a 125-nanometer range, including, in particular, optical signals having wavelengths at one end of the range and optical signals having wavelengths at a second end of the range.

摘要： An integrated optical waveguide is constructed from a lithium niobate (LiNbO.sub.3) crystal substrate. In preferred embodiments, a diffused layer is formed proximate to one surface of the substrate by sputtering a thin layer of a zinc-related oxide (e.g., ZnO, ZnLiNbO.sub.4, or the like) onto the surface and then annealing the substrate. The resulting concentration of zinc in the diffused layer forms a waveguide having desirable optical propagation characteristics. The substrate is preferably congruent lithium niobate. In particularly preferred embodiments, the substrate is magnesium oxide (MgO) doped lithium niobate.

摘要： In a method of amplifying optical input signals over a wide bandwidth, the optical input signals are applied to an optical waveguide made from a rare-earth-doped amorphous yttrium aluminum oxide material (e.g., erbium-doped yttrium aluminum oxide material). The optical input signals include optical signals having wavelengths shorter than 1,520 nanometers and optical signals having wavelengths longer than 1,610 nanometers. Preferably, the wavelengths range from as short as approximately 1,480 nanometers to as long as approximately 1,650 nanometers. Pump light is applied to the optical waveguide to cause the waveguide to provide optical gain to the optical input signals. The optical gain causes the optical signals to be amplified within the waveguide to provide amplified optical signals over the extended range from approximately 1,480 nanometers to approximately 1,650 nanometers, including, in particular, optical signals having wavelengths shorter than 1,520 nanometers and optical signals having wavelengths longer than 1,610 nanometers. Alternatively, the wavelengths of the optical input signals may be in the range from approximately 1,480 nanometers to approximately 1,565 nanometers. As a further alternative, the wavelengths of the optical input signals may be in the range from approximately 1,565 nanometers to approximately 1,650 nanometers.

摘要： An apparatus and method for nonlinear frequency mixing of light waves relying on a nonlinear material having a nonlinear coefficient d and a waveguide fabricated in the nonlinear material. The waveguide is equipped with a quasi-phase-matching (QPM) grating extending along the length of the waveguide and endowed with an asymmetry of the nonlinear coefficient d along the width of the waveguide. The transverse asymmetry is chosen to establish a mode overlap for nonlinear frequency mixing between different transverse width modes of light. The transverse asymmetry can be odd or else neither odd nor even so as to establish mode overlap for frequency mixing between even transverse width modes and odd transverse width modes. The QPM grating can have single or multiple grating stripes that can be staggered, interleaved, angled and otherwise altered to achieve the transverse asymmetry establishing a mode overlap for frequency mixing between even transverse width modes and odd transverse width modes.

摘要： A compensated nonlinear optical frequency mixer for compensating the walk-off produced by group velocity mismatch (GVM) between interaction waves. The compensated mixer has a first mixing region in which the interaction waves participate in a non-linear optical mixing process and where walk-off occurs between the interaction waves due to GVM. The compensated mixer is equipped with a frequency selective coupling and time delay structure located after the first mixing region for eliminating the walk-off produced between the interaction waves in the first mixing region by guiding the waves in arms whose lengths differ by a re-synchronization length. A second mixing region is located after the frequency-selective coupling and time delay structure, such that when the waves emerge in phase from the frequency selective coupling and time delay structure they continue to interact efficiently in the second mixing region. The compensated nonlinear optical frequency mixer of the invention can by used to compensate for GVM in frequency mixing operations involving a material's &khgr;(2) susceptibility.

摘要： A multiple-wavelength ultrashort-pulse laser system includes a laser generator producing ultrashort pulses at a fixed wavelength, and at least one and preferably a plurality of wavelength-conversion channels. Preferably, a fiber laser system is used for generating single-wavelength, ultrashort pulses. An optical split switch matrix directs the pulses from the laser generator into at least one of the wavelength conversion channels. An optical combining switch matrix is disposed downstream of the wavelength-conversion channels and combines outputs from separate wavelength-conversion channels into a single output channel. Preferably, waveguides formed in a ferroelectric substrate by titanium indiffusion (TI) and/or proton exchange (PE) form the wavelength-conversion channels and the splitting and combining matrices. Use of the waveguide allows efficient optical parametric generation to occur in the wavelength-conversion channels at pulse energies achievable with a mode-locked laser source. The multiple-wavelength laser system can replace a plurality of different, single-wavelength laser systems. In its simplest form, the system can be used to convert the laser wavelength to a more favorable wavelength. For example, pulses generated at 1.55 &mgr;m by a mode-locked erbium fiber laser can be converted to 1.3 &mgr;m for use in optical coherence tomography or to wavelengths suitable for use in a display, printing or machining system.
