MAGIQ TECHNOLOGIES, INC. — Department of Defense SBIR Phase I: AF182-105

Description

Analog-to-digital converters (ADC’s) are ubiquitous, critical components of modern information technology. ADCs convert analog signals such as radar, communication, astronomy and geo-science sensing into digital format, which can be easily processed by computer, FPGA or DSP. Limited by many electronic constraints, traditional ADCs cannot work well in a high frequency regime. In this proposal, MagiQ technologies Inc. will provide a photonic quantizer for high speed pADC. Our photonic quantizer will be fabricated on a monolithic wafer by integrated photonic circuit (IPC) technology with these unique advantages: optical 0/1 output; fast quantizing speed to tens Gs/s; low quantized value to 10�W, simple structure to obtain high ENOB to ten bits on the same wafer (InP); low operating power to 10mW per bit; intrinsic logic NOT and XOR property. In Phase I, we will study the photonic quantizer for RF/microwave applications. The proof-of-concept bench-top module has been made by an SOA and passive fiber components, that can build the quantizer and logic circuit for a pADC. We will demonstrate the feasibility of the key components and provide the design for further work in Phase II.
