Latest Patents

Kaplan's latest patents include a "Write with Light Optical Notching Filter" and an "Optical RF Filtering System." The write with light optical notching filter is designed to provide a linear phase and amplitude response, making it suitable for high-speed adaptive filtering. This system effectively filters out noise and signals that are not of interest, particularly in applications involving Radio Frequency (RF) signals used in communications and radar systems. The innovative design of this optical notching filter system is more compact than similar systems, reducing complexity and power requirements. Additionally, it can operate with both monochromatic and polychromatic light sources, allowing for flexibility in its application.

The optical RF filtering system patent describes a method where a band of radio frequencies is modulated by a laser beam, which is then optically Fourier transformed. This system utilizes a programmable optical notching filter to eliminate electromagnetic interference noise, ultimately down-converting the filtered beam to the original input signal minus the interference.
