Real photonic waveguides are affected by structural imperfections due to fabrication
tolerances that cause scattering phenomena when the light propagates through. These …

A two-dimensional optical-phased array is demonstrated by using a multiple-input star
coupler, compatible with FMCW LiDAR. Previous approach using a single-input design …

Sidewall roughness in optical waveguides represents a severe impairment for the proper
functionality of photonic integrated circuits. The interaction between the propagating mode …

We discuss the design and demonstration of 4-channel coarse wavelength-division (de-)
multiplexers based on cascaded Mach–Zehnder interferometer (MZI) lattice filters and …

In this paper we present a novel single-step RIE process for InP membrane optical
waveguide etching. The optimization of the process is focused on the sidewall verticality and …

Low-excess-loss arrayed waveguide gratings are enabled by unique application of deep UV
lithography in InP integrated photonics through reduced feature sizes and, more specifically …

In this paper, a model for the analysis and design of a reflective Arrayed Waveguide Grating
is presented. The device consists of one half of a regular AWG where each arm waveguide …

In this paper, a crosstalk-mitigated transmission scheme in arrayed waveguide grating router
(AWGR) based two dimensional infrared beam-steered optical wireless communication …

A compact demodulator for wavelength division multiplexed (WDM)-differential phase shift
keying signals monolithically integrated in an InP platform with a semiconductor optical pre …

The chapter reviews all relevant filters (to be) used in fibre optic communication and covers
generic filter structures including fibre coupler filters and Mach-Zehnder interferometers …
