Latest Patents

Odagawa's latest patents include a method to tune the emission wavelength of a wavelength tunable laser apparatus. This innovative laser apparatus integrates a wavelength tunable laser diode (t-LD) with a semiconductor optical amplifier (SOA) and features a wavelength monitor that includes an etalon filter. The current emission wavelength is determined by the ratio of the magnitude of a filtered beam passing through the etalon filter to a raw beam that does not pass through it. The method involves setting the SOA in an absorbing mode to sense stray components that may disturb the wavelength monitor. Subsequently, it corrects the ratio of the beams by subtracting the contribution from the stray component.
