摘要： A waveguide device for optical amplification and light amplification by stimulated emission radiation comprises an optical medium formed from a bulk glass. The optical medium is fused to a planar substrate to form a lower cladding. The bulk glass is subsequently thinned, patterned and coated with an upper cladding to form waveguide channels with sufficient mode confinement and mode field dimension compatible with direct coupling to optical fibers to achieve low insertion loss and a reduced polarization dependent loss, while obviating the need for critical fiber alignment using lensed or tapered fibers. The bulk glass is preferably an Er-doped or ErnullYb co-doped bulk glass, which when fused to quartz, or other low refractive index glass or cladding, provides a gain region less than about 5 cm long that is strongly index-guided to better confine the pump beam, and in the case of an amplifier, the signal beam.

摘要： A receiver employs non-linear threshold compensation to adjust input sample values from a single mode fiber to mitigate effects of polarization mode dispersion. A difference S between values for i) a decision for the current input sample and ii) a decision for the previous input sample is generated that indicates whether a transition between logic values occurred in the input data and the direction of transition (sign/phase). Two values are generated to determine a magnitude c of correction combined with the sign/phase (difference S) to generate a correction value. An error value e is generated as the magnitude of the difference between i) the decision for the input sample and ii) the input sample. A value d is calculated as the magnitude of the difference between i) the current input sample and ii) the previous input sample is also generated. The value d represents a relative nullclosenessnull in value between two consecutive input samples. A magnitude c of correction combined with S is dependent upon the current states of S, e, and d and is based on detection of the presence or absence of a data transition, closeness in value between two consecutive input samples, and the error between the current sample and the decision for the current sample. The correction value is then combined with the current sample yk to generate a compensated sample. A hard decision is then generated for the compensated sample. Observation of transmitted data patterns for bit combinations through a single mode fiber at the transmission rate, e.g., 10 Gbps, allows for generation of a table of rules to determine the threshold levels L of each decision device. As decisions are generated for data, threshold value L may then be modified given the decisions for previous samples.

摘要： A method of fabricating an integrated optical device and such a device, comprising a structure including at least one waveguiding element are presented. A basic structure is formed containing a substrate material carrying a buffer material layer coated with a core material layer of a higher refraction index as compared to that of the buffer layer. The at least one waveguiding element is defined in a guiding layer on top of the basic structure. The guiding layer is made of a material with a refractive index higher than the refractive index of the buffer layer and the core layer, and is chosen so as to minimize a height of the at least one waveguiding element and to provide effective guiding of light in the core layer. A cladding layer is formed on top of the so-obtained structure, wherein a height difference between the cladding layer region above the waveguiding element and the cladding layer region outside the waveguiding element is substantially small resulting in a desired flatness of the top cladding layer to allow direct formation of a further waveguide structure thereon and prevent significant perturbations in light propagation within the further waveguide structure.

摘要： In the monolithically integrated photonic circuit, light travels through multiple quantum well channel waveguides and is coupled into and out of the devices that reside in common on a single semiconductor substrate. Each device, which is co-planar with any other device on the substrate, is comprised of a quantum well channel waveguide of a pre-determined length and an electrical contact pad mounted on the waveguide that facilitates the application of electric field to the device. The function of any particular device as an optical source, an optical modulator or a photo-detector is determined by the bias mode of electric field applied to that particular device. The circuit is comprised of multiple rows of such devices. Each of these rows contains at least three devices which function as an optical source, an optical modulator and a photo-detector, respectively, and are separated from each other by electrical isolation gaps.
