Latest Patents
Kapulainen holds a patent for a "Method for controlling an optoelectronic component." This method involves two waveguides, where the refractive index of the first waveguide is periodically altered using a first control signal. The amplitude of this signal varies between a first amplitude level and a higher second amplitude level. Similarly, the refractive index of the second waveguide is adjusted with a second control signal, which changes between the first amplitude level and a lower third amplitude level. When both control signals are at their common first amplitude level, the refractive indices of the waveguides are equal, resulting in a zero phase difference. However, when the first control signal reaches the second amplitude level and the second control signal drops to the third amplitude level, the refractive indices become unequal, creating a predetermined target phase difference.
