Flexible Pulse Amplitude Modulation (FlexPAM) consists of the use of non-standard PAM formats, such as PAM-5 or PAM-6, to increase the granularity of the link capacity for a given baud rate. In this paper, we demonstrate FlexPAM systems as a scalable

Laser simulation and mask layout for photonic integrated circuits (PICs) typically take place in different design environments. This disconnect impairment can easily lead to laser designs that do not comply with manufacturing constraints, or errors i

EPJ Quantum Technology, 10 . ISSN 2196-0763
This work presents the results from the experimental evaluation of a quantum random number generator circuit over a period of 300 minutes based on a single chip fabricated on the InP platform. The circuit layout contains a gain switched laser diode (

We designed a series of AlInGaAs MQW laser layerstacks in order to investigate the influence of various design parameters (such as amount of quantum wells, doping strategy, SCH profile) on the laser performance. The stacks are experimentally evaluate

We propose a novel FMCW LiDAR Photonic Integrated Circuit that relies on slanted grating couplers. Our simulations on an SOI waveguide structure show that the concept is feasible with a FOV of 100 ◦ by 12 ◦ .
