“…Previously proposed DWA systems include the sequential scheduling algorithm [8], which emulates a virtual global first-in-first-out queuing for all incoming requests, and assigns a suitable wavelength for each request. This scheduling algorithm may suffer from wasted bandwidth and poor fairness guarantee if some ONUs have large Round Trip Times (RTTs).…”

“…The protection mechanism for the PON topology constructs the backup links or nodes to recover the failure. The authors of [8], [13] provide recovery mechanism against fiber-cut of feeder fiber which connects RN and OLT. H. Nakamura et al [13] presented the protection fiber for feeder fibers to avoid the fiber-cut situation.…”

Abstract-This study proposes a novel fault-tolerant architecture in WDM-EPON, Cost-based Fault-tolerant WDM-EPON (CFT-WDM-EPON), to provide overall protection. The CFT-WDM-EPON only equips a backup feeder fiber to recover the system failure. Additionally, a prediction-based fair wavelength and bandwidth allocation (PFWBA) scheme is also proposed to enhance the differentiated services for WDM-EPON based on the Dynamic Wavelength Allocation (DWA) and Prediction-based Fair Excessive Bandwidth Reallocation (PFEBR) which is our previous work. The PFEBR involves an Early-DBA mechanism, which improves prediction accuracy by delaying report messages of unstable traffic ONUs, and assigns linear estimation credit to predict the arrival of traffic during waiting time. The DWA can operate in coordination with an unstable degree list to allocate the available time of wavelength precisely. Simulation results show that the proposed PFWBA scheme outperforms the WDM IPACT-ST with a single polling table and the Dynamic wavelength and bandwidth 3 (DWBA3) in terms of end-to-end delay and jitter performance.

Abstract-We report a monolithically integrated InGaAsP DBR ridge waveguide laser that uses the quantum-confined Stark effect (QCSE) to achieve fast tuning response. The laser incorporates three sections: a forward-biased gain section, a reverse-biased phase section, and a reverse-biased DBR tuning section. The laser behavior is modeled using transmission matrix equations and tuning over ∼8 nm is predicted. Devices were fabricated using postgrowth shallow ion implantation to reduce the loss in the phase and DBR sections by quantum well intermixing. The lasing wavelength was measured while varying the reverse bias of the phase and DBR sections in the range 0 V to <−2.5 V. Tuning was noncontinuous over a ∼7-nm-wavelength range, with a side-mode suppression ratio of ∼20 dB. Coupled cavity effects due to the fabrication method used introduced discontinuities in tuning. The frequency modulation (FM) response was measured to be uniform within ±2 dB over the frequency range 10 MHz to 10 GHz, indicating that tuning times of 100 ps are possible.Index Terms-Integrated optics, ion implantation, laser tuning, quantum-confined Stark effect (QCSE), quantum well intermixing (QWI), tuneable semiconductor lasers.
