    Abstract: A modulated diode-laser provides a first sequence of optical pulses. The first sequence of optical pulses is further modulated to provide a second sequence of optical pulses. Pulses in the second sequence have a shorter duration than pulses in the first sequence. The first sequence of pulses may be generated by a directly modulated diode laser (12) or by a cw diode laser (42) with subsequent external modulator (48). Modulators external to the diode laser may comprise either a modulated double pass semiconductor optical amplifier (22, 48) or an electro-optical modulator (32). Nanosecond pulses with high output contrast ratio and defined spectral width can be generated.

    Abstract: A high capacity optical transmitter implemented on a photonic integrated circuit chip comprises' a single light source (108) which supplies a continuous wave having a particular wavelength to a plurality of modulators (106,112,126,130) to form modulated optical information signals. A phase shifter (114,128) is coupled to at least one of ' the modulators and' is used to shift the phase of the corresponding modulated optical information signal associated with a particular modulator. A polarization beam combiner (138) receives each of the modulated optical information signals from the modulators and the modulated optical information signal from the phase shifter and combines each of these signals to form a polarization multiplexed differential quadrature phase-shift keying signal. The light source, the plurality of modulators, the phase shifter and the polarization beam combiner are all integrated on the chip.

    Abstract: A coolerless photonic integrated circuit (PIC), such as a semiconductor electro-absorption modulator/laser (EML) or a coolerless optical transmitter photonic integrated circuit (TxPIC), may be operated over a wide temperature range at temperatures higher then room temperature without the need for ambient cooling or hermetic packaging. Since there is large scale integration of N optical transmission signal WDM channels on a TxPIC chip, a new DWDM system approach with novel sensing schemes and adaptive algorithms provides intelligent control of the PIC to optimize its performance and to allow optical transmitter and receiver modules in DWDM systems to operate uncooled. Moreover, the wavelength grid of the on-chip channel laser sources may thermally float within a WDM wavelength band where the individual emission wavelengths of the laser sources are not fired to wavelength peaks along a standardized wavelength grid but rather may move about with changes in ambient temperature. However, control is maintained such that the channel spectral spacing between channels across multiple signal channels, whether such spacing is periodic or aperiodic, between adjacent laser sources in the thermally floating wavelength grid are maintained in a firmed relationship. Means are then provided at an optical receiver to discover and lock onto floating wavelength grid of transmitted WDM signals and thereafter demultiplex the transmitted WDM signals for OE conversion.
