Intensity Noise in a Wavelength-Locked Fabry–Perot Laser Diode to a Spectrum Sliced ASE

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

“…On the contrary, it will become a drawback if the master source has a higher RIN than the slave. This is exactly the case when the optical injection is performed with a spectrally-sliced BLS as it was recently proposed for WDM access system [4]. The RIN floor of a spectrally-sliced BLS is of the order -110 dBc/Hz.…”

“…This proposal is attractive due to its low-cost and simple implementation. On the other side, since the BLS-based master sources inherently suffers from high intensity noise, the speed of BLS-injected FP LD is typically limited to 1.25 Gb/s [4]. However, with the needs of everincreasing bandwidth in access networks, this data rate seems to be insufficient in the next future.…”

A WDM-PON with an 80 Gb/s capacity based on wavelength-locked Fabry-Perot laser diode

“…This is mainly due to high PDG of the F-P LDs. However, at high injection power, the PDG of the PI F-P LD decreases and the RIN becomes better than that of the RSOA, since there is resonant enhancement of the field for the PI F-P LD [14].…”

Lasing wavelength shift of ASE‐injected wavelength‐locked F‐P LD in WDM‐PON

“…Wavelength division multiplexed passive optical network (WDM‐PON) has been considered a promising solution as broadband access networks due to the far greater capacity and flexibility. We have proposed the WDM‐PON based on the amplified spontaneous emission (ASE)‐injected wavelength‐locked Fabry‐Perot laser‐diodes (F‐P LD) [1], which has gained great attention due to the low cost and color‐free characteristics [2–10]. With the injection of a spectrum‐sliced ASE source, one cavity mode of the F‐P LD can be locked and enhanced in intensity, whereas the other cavity modes are suppressed, leading to single‐mode operation.…”
