Latest Patents

One of Takada's latest patents is a low-coherence reflectometer with polarization control. This invention utilizes a photocoupler to split light from a low-coherence light source into measuring light (DL) and local oscillator light (KL). The photocoupler receives the measuring light and inputs it into an optical circuit for measurement. It also splits the reflected light (RL) and employs a polarization controller to manage the state of polarization of the reflected light. Additionally, the local oscillator light is directed onto a reflector mirror, where it is split and combined with the reflected light, allowing for precise measurements. Another notable patent is the low-coherent reflectometer itself, which employs low-coherent beams to measure reflectance and reflecting positions in relation to an optical circuit. This system branches the low-coherent beams to produce measurement and local beams, facilitating accurate analysis of the optical circuit.
