Optical phase locked loop (OPLL) photonic integrated circuits (PIC) are critical for the high dynamic range phase modulated RF/photonic links. They provide for linear phase demodulation. A challenge for implementing the OPLL PICs is how to reduce the

A novel optical frequency down-conversion approach employing the quadratic electrooptic effect is proposed, analyzed, and verified. This down-conversion method can seamlessly integrate with an optical phase-locked-loop linear phase demodulator. It ha

Composite-cavity electro-optic microchip lasers have been proposed as a source for high-speed, low-noise microwave and optical signals. Such signals can be produced from a single short-cavity laser using the coupled optoelectronic oscillation archite

Using the Maxwell-Bloch equations, we have studied dynamics associated with an electro-optically tunable laser modulated by a sinusoidal signal with a frequency near the cavity free spectral range. We find that frequency modulation (FM) modelocking m

The dynamics of a short-cavity, electrooptically tunable microchip laser is studied using the Maxwell-Bloch equations for a unidirectional ring cavity. Within this model, the electrooptic tuning medium is treated rigorously by a wave propagation equa

Future communication systems will require high data rates and flexible modulation. Direct optical phase modulation of two microchip lasers by information-bearing signals allows for high-rate delivery via fiber to a basestation. At the basestation, th

We present the design and the first experimental results from a new device where an entire RF/photonic link is fabricated as a monolithic photonic integrated circuit (PIC). This novel “link-on-chip” PIC can operate in a linear mode or a mixer mod
