TECHNICAL ABSTRACT
Optoelectronic integrated holds the key to higher performance, reduced mass and radiation-hard space systems. A special need is increased flexibility of phased arrays for communication and detection. Currently RF arrays use ferrite waveguide elements for phase shifting which are both bulky and lossy with a phase shift limit of 360Âş . Light Detection and Ranging (LIDAR) arrays currently use a single optical source with mechanical steering. An identified goal would be an RF array with true time delay for beam steering and combined in the same physical location with an optical array steered via optical phase shift. ODIS approaches this problem with an optoelectronic circuit that integrates the RF and optical elements within a single chip. The RF at Ka band is generated by an optoelectronic oscillator and converted to RF power in a photodiode at the antenna element. The antenna element is a printed dipole on chip with dimensions of λ/2 (≈4.3mm). The optical source is an array of vertical cavity lasers spaced sufficiently closely to achieve a coherent beam. Optical beam steering is achieved by optical phase shifting of the coherent beam. In this SBIR, ODIS will demonstrate the key components integration to achieve a common RF/optical aperture.

POTENTIAL NASA COMMERCIAL APPLICATIONS
NASA applications are focused on the need for combined Rf and optical sensing. Current and future satellites require a multitude of sensors mounted an the satellite external surfaces covering wide bands in the mm wave band and separately in the optical spectrum. Sensing is central to the NASA mission. The POET technology base has great potential to address this sensing with unique ability to collapse the sensors into a single aperture. Simultaneously POET address many internal computational requirements related to on-board communications.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS
Phased arrays with electronic scanning represent a huge future commercial market in the wireless, security and free space optics communications industries. The optoelectronic integration platform being developed here provides a cost effective approach to combine optical and electronic device capabilities from which to generate the components for computer buses, AD converters, optical data links, optical switching matrices, optical routers, optical memories and many more yet to be identified. The integrated approach is the key to reduced cost and improved reliability.

TECHNICAL ABSTRACT
Optoelectronic integrated circuits offer radiation-hard solutions for satellite systems with much improved SWPB (size, weight, power and bandwidth). The phased array for sensing and data transfer is one system that optoelectronics can impact in the near term. It is known that optical delay could enable optimum beam steering electronic scanning . Lidar is another sensing system using optical beams that requires mechanical steering. In this SBIR a new integrated circuit technology is applied to the RF array with true time delay for beam steering and combined in the same physical location with an optical beam steered via current control. The integrated components required are lasers, amplifiers, modulators, detectors and optical waveguide switches. The RF at Ka band is generated by an optoelectronic oscillator and converted to RF power in a photodiode at the antenna element. The antenna element is a printed dipole on chip with optimized dimensions Ka band operation. The optical source is an array of vertical cavity lasers closely spaced and coupled by anti-guiding to enable coherent operation. Optical beam steering is achieved by controlling the current in a 2D array. In this SBIR, ODIS will develop the key components integration to produce common RF/optical aperture operation.

POTENTIAL NASA COMMERCIAL APPLICATIONS
NASA applications encompass the entire range of integrated systems in space combining both optical and electronic capability. Current and future satellites include 1)sensing in the uv, visible, NIR, MWIR, LWIR, VLWIR, 2)radar and communications in the mmw ¿¿ THz region, 3)computation and digital signal processing, 3)laser communications transceiver functions and fiber optic interconnect throughout the satellite, 3)all-optical-switching including the router, the switching fabric and the control function and 4)optical arrays. A prominent application is the RF phased array combined with optical arrays in the same aperture which represent a multitude of sensors mounted on the satellite external surfaces covering wide bands in the mm wave band and separately in the optical spectrum. The POET technology base has great potential to address this sensing with unique ability to collapse the sensors into a single aperture. Simultaneously POET address many internal computational requirements related to on-board communications.
