10 Gbit/s tunable dual-wavelength nonreturn-to-zero-to-return-to-zero data-format transformer based on a non-direct-current-biased fabry-perot laser diode.

All-optical NRZ-to-PRZ format transformer with an injection-locked Fabry-Perot laser diode at unlasing condition.

By using an optical nonreturn-to-zero (NRZ) format data-stream to injection-lock an synchronously modulated Fabry-Perot laser diode at below threshold condition (without DC driving current), an output data-stream with pseudo-return-to-zero (PRZ) format can be generated at bit rate of up to 2.488 Gbit/s. Such an NRZ-to-PRZ format transformation is due to the injectionlocking induced gain-switchi...

A pulsated weak-resonant-cavity laser diode with transient wavelength scanning and tracking for injection-locked RZ transmission.

By spectrally slicing a single longitudinal-mode from a master weak-resonant-cavity Fabry-Perot laser diode with transient wavelength scanning and tracking functions, the broadened self-injection-locking of a slave weak-resonant-cavity Fabry-Perot laser diode is demonstrated to achieve bi-directional transmission in a 200-GHz array-waveguide-grating channelized dense-wavelength-division-multipl...

Tunable Dual-Wavelength Laser Scheme by Optical-Injection Fabry-Perot Laser Diode

Frequency tracking and stabilization of a tunable dual-wavelength external-cavity diode laser

We show a unique dual-wavelength external-cavity laser diode with frequency tracking capability and obtain a stable beat frequency between the dual-wavelength output. By using a Fabry–Perot interferometer as the frequency discriminator and the time-gating technique in a servo loop, the peak-to-peak frequency fluctuations were stabilized, with respect to the Fabry–Perot cavity, to 86 kHz in the ...

30-Gbit/s downstream capacity of cost- effective colorless WDM-PON based on injection-locked Fabry-Perot lasers

A 100 GHz spaced comb, generated by a quantum dash passively modelocked laser (QD-MLL), is used as a low-noise coherent seeding source for colorless wavelength-division-multiplexed passive optical network (WDMPON) based on injection-locked Fabry-Perot laser diodes (IL-FP). Error-free downstream transmission over 25 km single-mode fiber (SMF) of 12 WDM channels at 2.5 Gbit/s with 100 GHz channel...
