The distribution of the multiple paths being such that the volume occupied by said multiple paths inside the amplifier medium substantially overlaps with the volume of the amplifier medium being optically pumped by an optical pump beam. Also, the distribution of said optical paths being such that no more than two of the multiple paths lie in a same plane.

摘要： A light-emitting system comprises a rare earth-containing organic light-emitting device (10, 11, 12, 13) fabricated on a silicon-based substrate (1). The light-emitting device is associated with a resonant cavity which may be in the form of a ridge or buried ridge waveguide (6). A diode (27) may form a modulator region (26) for injection of free carriers into the waveguide. This changes the refractive index or local absorption of the resonant cavity and thus allows switching of the system. The system is preferably a laser operating at about 1.5 νm although other wavelengths may be used. The wavelength is selected by the rare earth used.

摘要： Optical structures and method for producing tunable waveguide lasers. In one embodiment, a waveguide is defined within a glass substrate doped with a rare-earth element or elements by ion diffusion. Feedback elements such as mirrors or reflection gratings in the waveguide further define a laser-resonator cavity so that laser light is output from the waveguide when pumped optically or otherwise. Means are disclosed for varying the wavelengths reflected by the reflection gratings and varying the effective length of the resonator cavity to thereby tune the laser to a selected wavelength. Apparatus and method for integrating rare-earth doped lasers and optics on glass substrates. The invention includes a laser component formed from a glass substrate doped with a optically active lanthanides species with a plurality of waveguides defined by channels within the substrate. The laser component may constitute a monolithic array of individual waveguides in which the waveguides of the array form laser resonator cavities with differing resonance characteristics. The channels defining the waveguides are created by exposing a surface of the substrate to an ion-exchange solvent through a mask layer having a plurality of line apertures corresponding to the channels which are to be formed.

摘要： The invention concerns a power optical amplifier with planar waveguide optically pumped and a power laser using said amplifier. The amplifier planar waveguide comprises layers (14, 16, 18) forming a multimode guide with large numerical aperture for the pump light (4) and a monomode guide (16) for the light to be amplified (2). The latter is amplified in said guide by the optical pumping.

摘要： An optical repeater, in which an output level of each optical signal of WDM optical signals does not change even when the number of wavelengths of inputted WDM optical signals changes, which can be applied to a system in which intervals among WDM optical signals are relatively narrow, is provided. The optical signal repeater provides an optical signal amplifying means (2) for amplifying WDM optical signals transmitted from an optical transmitter via an optical fiber transmission line (1), a pumping light source (7) which outputs pumping light using for amplifying the WDM optical signals, an optical signal multiplexer (3) which transmits the pumping light to the optical signal amplifying means, an optical splitter (4) which splits the amplified WDM optical signals into two parts, a wavelength selection type reflection means (5) which reflects only an optical signal having a specified wavelength in one part of the amplified WDM optical signals split at the optical splitter, and an automatic output level controller (6) to which the optical signal having the specified wavelength is inputted and which controls the pumping light outputting from the pumping light source so that the power level of the optical signal having the specified wavelength reflected from the wavelength selection type reflection means becomes a designated level.

摘要： An optical waveguide doped with a rare earth element (12) is pumped (26, 28) so that an input optical signal (λ(w1)) is amplified as the input optical signal travels through the optical waveguide. The optical waveguide is provided with at least one light (λ(w2), λ(w5)) which, together with the input optical signal, causes four wave mixing (FWM) to occur in the optical waveguide. The FWM causes a converted optical signal to be produced in the optical waveguide. The converted optical signal has a wavelength different from the input optical signal. If the input signal is modulated by a transmission signal, then the converted optical signal will also be modulated by the transmission signal. The optical waveguide can be, for example, an erbium doped optical fiber operating as an erbium doped fiber amplifier (EDFA). Therefore, an EDFA can be used for both amplification and wavelength conversion.
