摘要： A continuously electronically tunable semiconductor laser has a lasing section, and first and second control sections separated from the lasing section by air gaps in a longitudinal arrangement. The longitudinal arrangement positions the lasing section between the two control sections, with the longitudinal arrangement corresponding to a lasing direction of the lasing section. The arrangement places longitudinal modes of the semiconductor laser in common with the longitudinal arrangement of the sections. Current is provided to each of the first and second control sections and the lasing section. Tuning is achieved by varying the current provided to at least one of the first control section, the second control section and the lasing section.

摘要： Technologies are generally described for implementing non-linear VCSEL equalization. In some examples, a rising edge tap parameter, a falling edge tap parameter, an equalization delay and a bias current may be used to equalize a data signal to be output from a VCSEL. A VCSEL model may be used to derive a VCSEL response to one or more isolated data pulses. The derived response may then be used to determine the rising and falling edge tap parameters and an equalization delay, based on a bias current value for the VCSEL and a data rate associated with the data signal. The data signal may then be adjusted based on the equalization delay and the rising and falling edge tap parameter and sent to the VCSEL for output. At the same time, the VCSEL may be biased with a bias current having the bias current value.

摘要： A tunable laser device (1) comprises integrally formed first and second ridge waveguides (5, 6). A longitudinally extending ridge (12) defines first and second light guiding regions (19, 20) of the first and second waveguides (5, 6) A plurality of first and second slots (27, 28) extending laterally in the ridge (12) adjacent the first and second waveguides (5, 6), produce first and second mirror loss spectra of the respective first and second waveguides (5, 6) with minimum peak values at respective first and second wavelength values. The spacing between the second slots (28) is different to that between the first slots (27) so that with one exception the minimum peak values of the first and second mirror loss spectrum occur at different wavelength values. The first and second waveguides (5, 6) are independently pumped with variable currents to selectively vary the common wavelength at which the minimum peak values of the first and second mirror loss spectra occur to produce Vernier tuning of the device.

摘要： To provide an oscillation device having a long oscillation wavelength in which wavelength variable width is relatively broad and wavelength sweep rate is relatively high. An oscillation device includes a gain medium having a gain with respect to an electromagnetic wave to be oscillated, cavity structures for resonating the electromagnetic wave, and energy injection means and for injecting pumping energy into the gain medium. The gain medium is sandwiched between a first negative permittivity medium and a second magnetic permittivity medium each of which real part of permittivity with respect to the electromagnetic wave is negative. Electric field application means is provided for at least one of the first negative permittivity medium and the second negative permittivity medium to apply an electric field for changing a depletion region formed at a boundary part with the gain medium.
