  • Publication number: 20250038476
    Abstract: An optical apparatus comprising a heat compensating device and a light generating optoelectronic device in thermal communication with each other. The heat compensating device is configured to provide heat compensation for the light generating optoelectronic device. An electrical circuitry provides first electrical signals to the light generating device and second electrical signals to the heat compensating device. The electrical circuitry is configured to adjust at least the second electrical signals to control a temperature of the light generating device. The electrical circuitry can adjust the second electrical signals using a feedback signal indicative of a measured wavelength of light generated by the light generating device. Adjusting the first electrical signals via different paths in a wavelength map can be used to calibrate the electrical circuitry so as to reduce or eliminate thermally induced hysteresis effects when tuning or scanning the wavelength of the light generating device.
