Title (EN) ISOTHERMAL THIN FILM HEATER
(FR) APPAREIL CHAUFFANT A FILM MINCE ISOTHERME
Abstract: front page image
(EN)Systems and methods for an isothermal thin film heater are provided. The isothermal thin film heater mitigates temperature variations in an optical circuit, such as an arrayed-waveguide grating. The thin film heater comprises a conductive plate and at least one heating element trace coupled to the conductive plate for heating the optical circuit. The heating element trace(s) is arranged around a periphery portion of the conductive plate such that concentric arcs are formed by the heating element trace(s). A sensor for sensing the temperature of the thin film heater and/or the optical circuit can also be provided.
(FR)L'invention concerne des systèmes et des procédés pour appareil chauffant à film mince isotherme. L'appareil réduit les variations de température dans un circuit optique, du type réseau de guide d'ondes en grille. Il comprend une plaque conductrice et au moins une trace d'élément chauffant couplée à la plaque pour le chauffage du circuit optique. La ou les traces se trouvent autour d'une partie périphérique de la plaque, de manière à former des arcs concentriques par le biais de cette trace ou de ces traces. On décrit aussi un capteur décelant la température de l'appareil et/ou du circuit optique.
