Description
Ring resonators generate an intensity modulation and stand for outstanding high-speed electro-optic conversion for applications in the C-band. Featuring a bandwidth beyond 110 GHz, this modulator has been proven working up to 170 GHz, which makes it a first choice for your next generation measurement system, radio-over-fiber communication or high data rate optical transport.
This modulator presents a spectrum with peaks and extinctions, which provides change of the operating point by tuning the wavelength of the laser source, making a bias voltage source unnecessary.
Delivered as a chip or semi-packaged chip, this product can be tailored to your needs.
