“…The fiber-coupled output power is more than 10.6 dBm of CW operation, and the output power variation is less than 0.6 dB for the whole tuning range. The fiber coupling efficiency was about 50% compared to I-L characteristics of an SGDBR laser integrated with an SOA [13].…”

We have demonstrated a high‐power widely tunable sampled grating distributed Bragg reflector (SGDBR) laser integrated monolithically with a semiconductor optical amplifier (SOA) having a lateral tapered waveguide, which is the first to emit a fiber‐coupled output power of more than 10 dBm using a planar buried heterostructure (PBH). The output facet reflectivity of the integrated SOA using a lateral tapered waveguide and two‐layer AR coating of TiO2 and SiO2 was lower than 3 × 10−4 over a wide bandwidth of 85 nm. The spectra of 40 channels spaced by 50 GHz within the tuning range of 33 nm were obtained by a precise control of SG and phase control currents. A side‐mode suppression ratio of more than 35 dB was obtained in the whole tuning range. Fiber‐coupled output power of more than 11 dBm and an output power variation of less than 1 dB were obtained for the whole tuning range.

A jumping search algorithm is applied to achieve a broadband visible antireflection coating design for a wide-angularincidence with an incident angle of up to 45 from the normal. It is shown that the maximum wide-angular visible spectral reflectance, obtained by different types of jumping search for a two-material 20-layer system, is reduced to less than 0.869% with 14-layer structures, and the maximum average visible spectral reflectance for incident angle lying in the range of 0 -45 is reduced to below 0.646%.
