TL;DR: The paper explains the concept of generic photonic integration technology using the technology developed by the COBRA research institute of TU Eindhoven as an example, and it describes the current status and prospects of generic InP-based integration technology.

TL;DR: In this article, the authors proposed a two-section polarization converter, which leads to doubling of the fabrication tolerances and wavelength range and promises conversion efficiencies above 99% over a wide range of fabrication and operation parameters.

TL;DR: In this article, a design study on an integrated optical circuit for a Brillouin optical time domain reflection readout unit with low-cost potential is presented, which contains narrow linewidth tuneable distributed Bragg reflector (DBR) lasers, photodiodes with an optical mixer for coherent detection, a 10-bit digitally switched delay line for frequency tuning, and a switching fabric that allows three modes of operation.

TL;DR: In this paper, an integrated polarization converter (PC) was added to a circuit containing optical amplifiers (SOAs) to obtain polarization independent amplification, which was achieved by placing the PC halfway between two identical SOA sections.

TL;DR: In this paper, the authors realized a low-cost optical fiber sensor read-out unit, which allows for measurement distance resolution of about 2 m along a sensing fiber using 25 ns wide pulses generated on chip.
