We utilize commercial semiconductor batch processing techniques to create our Broadband Optical Modulators
The Broadband Optical Modulator is a reflective diffraction grating with controllable groove depth which modulates intensity by switching between an unpowered flat mirror state and a powered diffractive-state.
Each device is designed for optimal performance up to its maximum deflection over a range of wavelengths. To attain peak extinction, the user simply tunes the deflection at a given wavelength. Modulators are designed to be operated using a well-conditioned high voltage source.
Our modulators are wavelength adjustable and have a frequency range of DC to 200kHz with full modulation and higher speeds with partial modulation. Use your Broadband Optical Modulator to replace a pockels cell or use it as a substitute for your acousto-optic or electro-optic modulator for applications that require higher throughput. MEMS modulators have proven versatility across various applications, and their performance can be customized to user specifications.
Choose from the Thorlabs High Speed Optical Modulator to provide high-speed intensity modulation and beam attenuation for your imaging application or the BMC Broadband Optical Modulator (BOM), for more custom applications.
"[The BMC] modulator is advantageous over the acousto-optic types because it is free from the dispersion effects and delivers better spatial resolution for the focused laser."
