External Optical Modulator Using a Low - cost Fabry - Perot Laser Diode for Optical Access Networks

External Optical Modulator Using a Low-cost Fabry-Perot LD for Multicasting in a WDM-PON

An external optical modulation using absorption nulls in a Fabry-Perot laser diode (FP-LD), has been proposed and experimentally demonstrated for multicasting in a WDM-PON. The center wavelengths of absorption nulls in an FP-LD move to short-wavelength rapidly by only a small current (~1 mA) injection. If the current injection is stopped, the nulls move back to the original position. Such a mov...

Wideband and frequency-tunable microwave generation using an optoelectronic oscillator incorporating a Fabry-Perot laser diode with external optical injection.

Wideband and frequency-tunable microwave signal generation using an optoelectronic oscillator incorporating a Fabry-Perot laser diode (FP-LD) with external optical injection is proposed and demonstrated. Through external injection, the FP-LD functions as a tunable high-Q photonic microwave filter, and the frequency tuning is realized by either tuning the wavelength of the externally injected op...

Using optical injection of Fabry-Perot lasers for high-speed access in optical telecommunications

In this paper we present our recent works on optical injection of Fabry-Perot laser diode for application in access networks. The injection-locked Fabry-Perot laser diode is used as low-cost colorless transmitters for high-speed optical access exploiting wavelength-division-multiplexing technology. The modification of main characteristics of Fabry-Perot laser such as spectral properties, noise ...

Cost-effective wavelength-tunable fiber laser using self-seeding Fabry-Perot laser diode.

We propose and experimentally demonstrate a continuous wave (CW) tunable-wavelength fiber laser using self-seeding Fabry-Perot laser diode (FP-LD) without optical amplifier inside gain cavity. By employing a tunable bandpass filter (TBF) and a fiber reflected mirror (FRM) within a gain cavity, the fiber laser can lase a single-longitudinal wavelength due to the self-seeding operation. The propo...
