Up to 45km-long Amplified Self-Seeded RSOA based External Cavity for 2.5Gb/s WDM PON transmission

High‐bit‐rate SOA‐based optical network unit with low seeding power that uses feedback seeding scheme

“…The result of the self-seeding scheme is incoherent light, which is suitable for low-data-rate communication. Moreover, an advantage of this scheme is that it saturates the RSOA, thus, suppresses the noise generated by the amplifier [10][11][12][13][14][15][16][17][18][19][20][21]. Although both remote seeding and self-seeding schemes provide flexible and low-cost solutions, they have some limitations.…”

“…SOAs are multifunctional devices [22][23][24][25]. They are widely used in optical communication systems as amplifiers [26,27], optical switches [22,28,29], inline optical detectors [30,31], wavelength shifters [32,33], or optical light source in colourless ONU [10][11][12][13][14][15][16][17][18][19][20][21]. SOA is only a few hundred μm long and it is compatible with other semiconductor devices for integration purpose.…”

Demystification of Self-seeded WDM Access

“…The mirror was placed after the demultiplexer, at the receiver side, removing the shared point. To overcome the added losses and improve the data cancellation, a saturated RSOA replaced the Faraday rotator mirror [11], [22]- [24] in a so called "face to face" configuration. Thus, a distance of 70 km at 2.5 Gb/s in the O band was achieved [24].…”

O-Band 10-Gb/s Operation of a Reflective Semiconductor Optical Amplifier Based Self-Seeded Transmitter for Optical Access Applications

“…The self-seeded approach based on reflective semiconductor optical amplifiers (RSOAs) offers self-tuning capability [4,5] together with wide-bandwidth colorless operation. It also presents immunity to Rayleigh backscattering, which, on the contrary, is part of the process of the creation of the transmitted signal [6].…”
