In this article, the potential of photonic integrated circuits (PICs) for modern gas sensing
applications is discussed. Optical detection systems can be found at the high-end of the …

We describe the design procedure, optimization, and fabrication cycle of an index-pattern FP
laser on an InP platform. The design parameters of the ridge and reflector (based on slots) …

Widely tunable Y-junction lasers have been realized in the wavelength range of 2.34-for
trace-gas sensing application. Y-junction structures with large bend radius and small length …

Photonic integrated circuits (PICs) have garnered a lot of interest due to their ability to offer
reductions in size, weight and power, improved performance and stability over discrete …

Data usage continues to rise exponentially with user demand, and the bandwidth of optical
communications is reaching its limit. Spectrally efficient advanced modulation formats are …

L-band SG-DBR lasers have wide application prospects in high-speed optical
communication and passive optical networks. In this paper, using InGaAsP as the passive …
