An ultra-wideband imaging system uses optical delay lines to create radio-frequency image pixels with smaller, lower-loss delay elements than electrical approaches.
A coherent optical receiver uses PLL-based phase tracking and oscillator-controlled demodulation to recover baseband signals from optical inputs.
An integrated Pound-Drever-Hall system stabilizes semiconductor laser frequency using an on-chip interferometric reference and feedback control.
A Quadrature Delay-Locked Oscillator that caters to increasing multi-GHz and multi-phase clock demands in systems such as time-interleaved architectures.
