Integrated optics sensors on glass

Integrated optics has been extensively used from the beginning for telecommunication applications. Depending on the functions to implement, different technologies have been employed. Among all of them, glass ion exchange is the cheapest, since both substrate and technological requirement are not expensive. Ion exchange technology has some advantages that can be very important for sensors applications. After a brief presentation of the different possible ion exchange, we will present some integrated optics sensors realized on glass that have been made in the past few years. We will give details about the particularity required for every applications. Then, we will give some informations about biological applications and we will conclude with some limitations of this technology.
