Optical transmission of microwave signals offers many advantages such as increased bandwidth; immunity to electromagnetic interference; reduction of size, weight and power consumption; and low, frequency independent loss over long distances. But microwave photonic links often lack the performance required to replace traditional microwave links. We present a microwave photonic link architecture that enables high gain and dynamic range, low noise figure, and multi-octave bandwidth operation. Our method uses double sideband suppressed carrier (DSB-SC) modulation together with a balanced coherent heterodyne detection scheme. The modulation method increases link linearity by producing amplitude modulation based on the optical field rather than intensity. The combination of carrier suppression, optical amplification, phase-locked local oscillator insertion, and balanced detection provide high performance microwave photonic links.

The photonic time-stretch technique can be used for achieving ADCs at higher frequencies by reducing power dissipation, and overcoming the barrier due to clock jitter and the limited speed of electronics. The TS-ADC can also be very useful in applications such as antenna remoting, since no additional hardware is required to provide the option of remoting in communications and radar systems. In this mode of operation, the dispersive fiber that stretches the RF signal can also serve as the fiber link. Optical subsystems are being developed for signal transmission at board levels and chip levels to reduce power dissipation and achieve high throughput rates.

These results demonstrate the ability of a commercial LiNbO3 EO modulator to withstand damage from direct pulsed RF input up to 200 W. However, short-term disruption occurred at a few Watts, which suggests a need for improved modulator thermal design.

Bandwidth intensive applications including scientific computing and real-time video processing are expected to strain data center networking infrastructure. Traditional solutions to increase capacity (high performance electrical components, dense WDM, high speed optical switching, over provisioning) are currently too costly. We are exploring a data center with a hybrid optical/electrical networking architecture that provides slowly reconfigurable high bandwidth connections [1,2,3]. We believe that such an architecture is widely applicable to emerging applications which often have relatively static communication patterns that change on human rather than packet time-scales. This architecture consists of traditional electronic components plus a relatively smaller number of higher bandwidth optical components (Figure 1). A new software layer between the application and the hardware will reconfigure the network automatically based on communication requirements provided by the application and the reconfigurable hardware components.

The concept of Free Space Optical (FSO) communications has been around since the late 1960's.This paper will describe some recent experimental results that demonstrate and validate hybrid FSO/RF communication links as viable components in a tactical high data rate network. In particular, we will describe air-mountain link closure up to ranges of 200 km under heavy atmospheric turbulence. These links were operated at low packet and bit error rates, with occasional link outages. Like the internet, we used retransmission to minimize the effect of these outages on link throughput. For example, when the FSO system is running, ORCA uses the RF system for retransmission to improve link efficiency. In addition, we will discuss potential losses created by the aircraft aero-optics effects. Finally, we will show comparison between model predictions and experimental data that suggest we can predict link performance if the atmospheric turbulence conditions are known.

Microwave photonic and carbon nanotube links may appear separately and synergistically in future military antenna systems. As photonic and CNT link performance continues to improve, RF photonics insertion into antenna systems may expand in areas including RF pre-processing and filtering, RF front-end technology, A/D conversion, true time delay (TTD) beam forming network for both manned and unmanned ISR applications.
