Abstract: A method of dynamically adjusting an optical module in an optical system including a plurality of transmission channels includes the following steps: measuring the quality of the optical signal at the output of the system as defined by an error function, varying an optical parameter of at least one module of the system, measuring a differential error introduced by each variation on the error function of the optical signal at the output of the system, estimating an operating point of the system corresponding to an expected reduction of the error function, and adjusting a parameter of an optical module toward the operating point of the system.
Abstract: A method of dynamically adjusting at least one optical module in an optical system including a plurality of transmission channels includes the following steps:
Abstract: A semiconductor optical component is disclosed which comprises a current injection region and at least one electrically isolated region referred to as a first plateau, each region containing a contact layer of an alloy based on gallium arsenide, GaAs, deposited on a semiconductor material upper confinement layer. The component further comprises in the first plateau a dielectric material isolation layer on top of the contact layer. An attachment layer is disposed between the contact layer and the isolation layer to increase the adhesion of the isolation layer to the contact layer. A method of fabricating the above kind of component is also disclosed.
