Definitions
- the present invention relates generally to optically active glass and light emitting devices including such glass. More specifically, the invention relates to phosphosilicate optical waveguides and high output power amplifiers or lasers including the same.
- Optical fiber lasers and amplifiers used in the amplification of light usually include optical fibers having optically active waveguiding cores doped with rare-earth active ions, such as for example, thulium, erbium, ytterbium and neodymium.
- rare-earth active ions such as for example, thulium, erbium, ytterbium and neodymium.
- Longitudinal mode beating can be an important source of high frequency noise which consequently gives rise to peak power fluctuations in the pulse structure of a pulsed amplifier or laser. Depending on its amplitude and frequency spectrum, this noise can severely limit the ability to generate stable optical pulses having special shapes with fine structures.
- a light-emitting device including a phosphosilicate optically-active glass.
- the core may have an outer region and an inner region, the outer region having a refractive index lower than a refractive index of the inner region.
- the light-emitting device may be a device that emits light or alternatively and additionally amplifies light.
- the light-emitting device may include an amplifier, wherein the amplifier includes the gain medium.
- the light-emitting device may include a laser, wherein the laser includes the gain medium.
- an optical waveguide for use in a light-emitting device, the optical waveguide comprising a gain medium including an optically-active phosphosilicate glass, wherein the phosphosilicate glass comprises at least one active ion dopant and from about 1 to 30 mol% of phosphorus oxide.
- the optical waveguide may comprise a core and at least one cladding surrounding the core, and the gain medium may include the core or at least one of the cladding.
- FIG. 1 A is a cross-sectional view of an optical waveguide of a light-emitting device, according to an embodiment of the invention.
- FIG. 1 B is a cross-sectional view of an optical waveguide of a light-emitting device, according to another embodiment of the invention.
- FIG. 5B is a diagram showing the measured loss upon slicing of a relay fiber to an optical waveguide according to the invention.
- FIG. 6 is a diagram of the refractive index profile along the diameter of a double- cladding optical waveguide and along the diameter of a triple-cladding optical waveguide according to embodiments of the invention, showing a reduced core numerical aperture for a triple-cladding optical waveguide.
- FIG. 7B is a diagram of the refractive index profile along the diameter of a core of an optical waveguide according to an embodiment of the invention, showing a stepped change in index of refraction.
- FIG. 7C is a diagram of the refractive index profile along the diameter of a core of an optical waveguide according to an embodiment of the invention, showing a gradual change in index of refraction.
- the light-emitting device may emit light and alternatively or additionally it may amplify light.
- the light-emitting device is preferably embodied by an amplifier or a pulsed amplifier, it may be embodied by a laser, a pulsed laser, an optical source of amplified spontaneously emitted (ASE) radiation, any continuous wave (CW) or quasi-continuous wave (quasi-CW) amplifier or laser, be it coherent or incoherent, or by any other means of amplification or generation (source) of light.
- a laser amplifies light by the stimulated emission of radiation. It includes a gain medium inside an optically cavity and means to supply, or pump, energy to the gain medium.
- the gain medium is a material with appropriate optical properties.
- the optical cavity causes the light to pass back and forth through the gain medium.
- Energy is pumped into the gain medium. This energy excites atoms in the gain medium to transition to a higher energy level, creating a population inversion.
- the photons stimulate the excited atoms to emit additional photons of the same wavelength and to decay down to a lower energy level, resulting in an amplification of the light.
