An integrated optical sensor for, for example, a (bio)chemical sensor has an optical waveguide (2) having at least two coupling regions (3, 5), which are separated by at least one measurement region (4). A first wave is excited in the waveguide (2) by the first coupling region (3) and passes through the measurement region (4) and the second coupling region (5). A second wave is excited in the second coupling region (5) and subsequently interferes with the first wave. Here, the reduction in amplitude of the first wave by the second coupling region (5) is less than 95%.
