Tensor learning is a powerful tool for big data analytics and machine learning, e.g., gene analysis and deep learning.

We report two uni-traveling-carrier photodiode (PD) structures, for high-power and high-linearity applications.

We have realised the first high-power quantum-dots tapered laser mini-bar, which delivers 14 W CW, with a narrow far-field angle of 3deg FWHM, and a reduced wavelength shift of 0.21 nm/K.

A 1.55 mum VECSEL with a metal-GaAs/AlAs hybrid metamorphic mirror optimized for high power operation has been assembled with a fast saturable absorber mirror (SESAM) in a four mirror cavity to gen

We have developed single frequency and single spatial mode laser structures with high optical power, using an aluminium free active region, which are to our knowledge the first demonstration for Cs

We have developed 852 nm laser structures, using an aluminium free active region.

These two transmitters are built according to the same general design, the former being for 60 kW and that at Kalundborg for 120 kW.

We demonstrate multiple-stage dual-illuminated traveling wave photodetectors in silicon photonics for high-power and high-speed applications.

Evanescently-coupled photodiodes were realised for high-power operation at a wavelength of 1.55 mu m and wide-band operation beyond 30 GHz.

We have fabricated and characterized two high-power high-linearity uni-traveling-carrier photodiode (UTC-PD) structures.
