Wavelength tunable laser diodes especially widely-tunable lasers are generally regarded as key components for future optical telecommunication systems. The advantages of monolithic tunable lasers compared to a series of single-frequency distributed feedback lasers (DFBs) are well known as both low-cost and high-performance [1]. However, these lasers require both high resolution processing and complex re-growth steps to manufacture. On the other hand, tunable lasers can be realized by distributing reflective defects (so-called slots) into conventional Fabry-Perot (FP) laser cavities. By carefully optimizing the slot positions and slot number, single mode laser lasing with a side mode suppression ratio (SMSR) of more than 40 dB has been achieved [2]
