“…Widely wavelength tunable lasers are key enablers of wavelength-division multiplexing (WDM) systems, with sampled grating distributed Bragg reflector (SG-DBR) [1] and distributed feedback (DFB) [2] laser arrays demonstrating wide tunability. Although tunable DFB and DBR lasers demonstrate good optical power and wavelength stability, the high-resolution processing and complex regrowth steps involved in their fabrication can result in low yield and high manufacturing costs [3].…”

Two distinct athermal bias current procedures based on thermal tuning are demonstrated for a low-cost, monotlithic, three section slotted single mode laser, achieving mode-hop free wavelength stability of ± 0.04 nm / 5 GH z over a temperature range of 8-47 • C. This is the first time that athermal performance has been demonstrated for a three-section slotted laser with simple fabrication, and is well within the 50 GHz grid spacing specified for DWDM systems. This performance is similar to experiments on more complex DS-DBR lasers, indicating that strong athermal performance can be achieved using our lower-cost three section devices. An analytical model and thermoreflectance measurements provide further insight into the operation of multi-section lasers and lay the foundation for an accurate predictive tool for optimising such devices for athermal operation.

Transmission performance is improving through the use of new modulation formats such as multi-level PSK, OFDM and coherent detection. ROADM, WSS, OXC and optical packet switching have been exploited for the node of fiber ring or mesh network topology to overcome the bottleneck of optical network. This paper reviews recent advances in optical devices for long haul and metropolitan area networks and describes milestones in optical technology. These developments in optical technology allow us to expand the broadband networks. Moreover, the progress made on photonic device performance enhances system performance. Sawada, and Y.

“…A modulation rate of 2.5 Gb/s was achieved for a wavelength spacing of 4 nm. For a laser array based on tunable lasers, Ishii et al demonstrated an integrated multi-wavelength array, which can cover 97 channels of a WDM system [41] . In 2014, a 100 Gb/s transmitter was realized by using a 10 × 10 Gb∕s hybrid integration DFB laser array with an array waveguide grating (AWG) [42] .…”
