摘要： A distributed feedback ridge waveguide semiconductor laser diode (10) having a waveguide region (22) with a typical thickness of at least 500 nanometers and an effective refractive index difference between the ridge structure (31) and exposed portions of the waveguide region (25) which surround the ridge structure of less than 0.001. This permits the width (W) of the ridge (31) to be expanded beyond 3.5 microns thus translating directly to higher power outputs at 1.55 νm wavelengths, where carrier diffusion and carrier heating limit current density injected into the active region (24).

摘要： A method of producing a planar waveguiding device having a core (10) and a cladding (21, 22, 23). The cladding has grooves (11, 12) directly interfacing (15, 16) with the core (10). A layer of core glass (10) is deposited on the surface of a substrate (24). This layer is etched to produce a shaped layer which includes a first core portion (10) having the same configuration as the intended core (10) and an expanded core portion (30) wherein the core glass extends beyond the intended core boundary. A glass covering layer (21) is deposited over the etched core glass and grooves (11, 12) are produced by etching through the covering layer (21) and into said expanded core portion (30). This removes the core glass (30) extending beyond the intended core (10) boundary to produce interfaces (15, 16) between the core (10) and the grooves (11, 12). All of the glasses are silica with additives to adjust the refractive index and/or the melting point.

摘要： An electro-optic interconnect for use with optical signals and a probe beam is disclosed. A plurality of first optoelectronic detectors responds to an optical signal and develops a plurality of first electrical signals. A probe laser generates the probe beam. Means are responsive to the plurality of first electrical signals and changes a characteristic of the optical probe beam. A second optoelectronic detector responds to the changed characteristic and develops an output electrical signal representative of the optical signals. Alternatively, the second optoelectronic detector can be eliminated and direct optical signal processing can be implemented. In another aspect, a time compensation network serves to synchronize the probe and the signal beams. The electro-optic interconnect can be configured to add and subtract the optical signals.

摘要： An optical pulse generator having a high order transfer function that comprises a first and a second nested interferometric modulator, each modulator comprising an optical input, an electrical input, a first arm, a second arm and an optical output. The second interferometric modulator is optically coupled into the second arm of the first interferometric modulator. The optical output of the first interferometric modulator generates pulses at a repetition rate that is proportional to a multiple of a frequency of an electrical signal applied to the electrical input of at least one of the first and second interferometric modulator and at a duty cycle that is inversely proportional to the order of the transfer function of the optical pulse generator. The multiple may be any integer equal to or greater than one.

The optical filter (1) comprises a first Mach-Zehnder interferometer (41) constituted by a first part of a main optical line (20), a first auxiliary optical line (21), and first and second optical couplers (31,32) which optically couple the main optical line (20) and first auxiliary optical line (21) to each other.

In particular, in order for the slope of loss spectrum in a signal wavelength band to be adjustable while being centered about the amount of loss of light at a reference wavelength propagating through the main optical line (20) from its entrance end (11) to exit end (12), at least one of the first part of main optical line (20) and the first auxiliary optical line (21) is provided with a first temperature regulating device (51), at least one of the second part of main optical line (20) and the second auxiliary optical line (22) is provided with a second temperature regulating device (53), and the first and second temperature regulating devices are controlled by a control system (100).
