AI Technical Summary

Problems solved by technology

Note that when light passes through the ERM it affects the current flow through the ERM and thus its effective resistance
This will affect crosstalk to passive waveguide sections and other ERMs

Embodiment Construction

[0039] figure 1 A schematic layout of a tunable laser commonly used in a photonic integrated circuit PIC is shown. The device 1 has three AMZIs 10, 20, 30, each AMZI has two ERMs 11, 12; 21, 22; 31, 32; its length is 2.118 mm, plus a so-called in-line ERM 40 to be tuned independently Cavity mold. All ERMs have 30 μm long isolation sections at both ends. ERMs operate using a voltage that puts the device's pin junctions under reverse bias. The layout also includes a semiconductor optical amplifier SOA41.

[0040] figure 2 The voltage levels measured on different electrorefractive modulator ERMs as a function of the voltage applied to the ERM in the long arm of the coarsely tuned AMZI are shown in 50 . Presented are the voltages recorded on the ERM, the short arm of the coarse-tuned AMZI in 51; the long arm of the medium AMZI in 52; and the long arm of the fine-tuned AMZI in 53. In 54, presented are the measured voltages on the fine-tuned AMZI when both ERMs in the cavity ...

Abstract

A photonic integrated circuit, PIC, comprising a plurality of semiconductor layers on a substrate, the plurality of semiconductor layers forming a PIN or PN doping structure, the PIC comprising a waveguide arranged for conducting light waves; an optical element connected to the waveguide, wherein the optical element, in operation, is in reverse-bias mode, and wherein the optical element comprises a contact layer arranged for connecting to a voltage source; wherein the waveguide comprises conducting contacts proximal to the optical element, and wherein the PIC further comprises at least one isolation section arranged in between the optical element and the conducting contacts. Corresponding methods of operation of such a PIC are also presented herein.

Description

technical field [0001] The present disclosure relates generally to the field of photonic integrated circuits, and in particular to an apparatus having a reduced level of interference between different components of a photonic integrated circuit. Background technique [0002] A photonic integrated circuit PIC or integrated optical circuit is a device that integrates multiple photonic functions. Its main difference from electronic integrated circuits is that PICs provide functionality for information signals applied at wavelengths of light in the visible or near-infrared spectrum. Different components such as low loss interconnecting waveguides, power splitters, optical amplifiers, optical modulators, filters, lasers and detectors form the PIC. In general, a PIC includes both active components as well as passive components. Active components are, for example, semiconductor optical amplifiers SOA, electro-refractive modulators ERM, and passive components are, for example, wav...
