Gain-coupled (GC)-DFB-LD tolerant to optical feedback was developed for low-cost, isolator-free optical subassembly module. GC-DFB-LD into isolator-free micro-BOSA module has power penalty less than 0 ...

The 67-year-old, who managed Manchester United for six months, had a routine ankle operation but picked up an infection after the wound became seriously inflamed ...

A monolithic integrated dual-wavelength DFB semiconductor laser is fabricated and experimentally demonstrated. Utilizing the reconstruction-equivalent chirp (REC) technique, dual-wavelength lasing is ...

A hybrid integrated III-V-on-Si sampled grating distributed feedback laser by flip-chip bonding an III-V gain chip to Si-on-insulator photonic integrated circuits is reported in this article. Light is ...

We have fabricated the thermally controlled, widely tunable laser module using matrix DFB laser. To realize high output power and wide tunability simultaneously, 12 DFB lasers were integrated in the ...

The approach is validated for conventional DFB lasers by comparing the calculated feedback sensitivity with those obtained from analytical expressions. Both feedback sensitivity and coherence collapse ...

We demonstrate of a metal grating purely index coupled distributed feedback quantum cascade Lasers at around 7.5mum. It presents a large tuning without broadband gain and side mode suppression ratio ...

Analytical expressions are derived for the amplified spontaneous emission of a DFB (distributed-feedback) semiconductor laser amplifier with reflective cavity ends. The analysis is extended to a ...

Bragg waveguide grating is one of the most important structures for on-chip light control. In order to achieve specific optical performances, the grating structure should be well designed with fine ...

A theoretical analysis of distributed feedback (DFB) lasers with mixed gain and index coupling (partly gain-coupled DFB) is given for perfect antireflection (AR) coatings. Analytical expressions for ...

We demonstrate a two-section distributed feedback (DFB) laser for direct modulation based on the reconstruction equivalent chirp (REC) technology. The two-section DFB laser exhibits a stable ...
