The presentation describes the progress made in the first two years of operation on technical goals, operational framework, and opportunities for the broader photonics community. The institute is providing a turn key capability to industrial customers with a primary focus on SMEs, universities and government agencies.
Radio frequency photonics is demonstrating superior performance in communication systems using discrete components. As systems establish an upgrade path balancing challenging bandwidth requirements with size, weight and power constraints, the time is ripe to transition to a more efficient and cost-effective hybrid manufacturing technology.
We provide an overview of electronic-photonic integration techniques and describe our recent work to develop monolithic and hybrid photonic components and integrated circuits (PICS) realized in several material platforms (silicon, silicon nitride, compound semiconductors) for a variety of government applications.
We propose and demonstrate a tunable optoelectronic oscillator (TOEO) based on Stimulated Brillouin scattering (SBS). By the joint of coupled double loops (CDLs), we not only increase the side-mode suppression ratio (SMSR) of the SBS-based TOEO, but also enhance the stability of the system.
In this paper, ultra-low noise hybrid lasers operating with high output power are demonstrated. These hybrid lasers provide very low relative intensity noise, below −165dB/Hz, extremely low phase noise, and Lorentzian linewidths as low as 15 Hz, enabling key RF Photonics and Optical Sensing applications.
Satellite communications are providing higher data rates through the use of higher frequency bands and higher order modulation schemes [1]. There may be a need to distribute antennas over hundreds of meters to kilometers, for example in a goniometric system for direction finding applications [2]. Radio frequency (RF) photonics may be used as a distributed gateway to access these high frequency bands...
There is a growing need for RADAR systems to address short range sensing problems where standard electro-optic sensors are impeded. From convoy situational awareness to rotorcraft brownout, there are a growing number of military requirements to address degraded visual environments (DVE) where new solutions are needed to provide feedback to the operator in both manned and unmanned platforms. In such...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Photonic systems are being increasingly designed for multi-functional, distributed avionic platforms to satisfy the next-generation military needs [1]. This approach requires establishing high-capacity, Free-Space Optical (FSO) communication networks that connect a variety of mobile and aerial platforms in an ad-hoc fashion [2]. Traditional design methodology, that addresses a specific scenario with...
Reflex Photonics Inc. has developed compact 40G full duplex (4+4) 10Gbps/lane optical fiber transceivers for harsh environment applications such as Aerospace and Defense. These products were made to be embedded on printed-circuit boards in close proximity to high speed electronics in high performance embedded computing systems to optimize their performance [1,2]. Going one step further, the industry...
The support of higher order modulation format such as 16-QAM and 64-QAMis an essential feature of next generation coherent optical transceivers to ensure a spectrally efficient and high capacity optical transmission [1–3]. In previous work, we have proposed an optical QAM transmitter scheme that employs QPSK modulators driven by binary electrical signals [4, 5]. This paper presents the design for...
A packaged phase modulator that has 3dB optical insertion loss and 7.5V Vπ at 40GHz has been successfully tested for >1W optical input power. A high-power, 40GHz modified uni-carrier traveling (MUTC) photodiode is fabricated and packaged. The developed components are discussed for analog photonic links.
Despite the high phase non-linearity of a Silicon Mach-Zehnder Modulator in forward bias, we demonstrate that high third order spur-free dynamic range ~102.8 dB. Hz2/3 can be obtained by optimizing the D.C. bias operating point at 1 GHz.
New architectures and simple configuration algorithms based on progressive single-parameter feedback loops allow complex photonic circuits to be set up and stabilized, and even to train themselves for complex tasks. Principles of such systems and current and potential applications will be discussed.
We present the design and analysis of a millimeter-wave photonic tightly coupled array. Simulations show it is possible to achieve good radiation efficiency across several of the frequency bands spanning 15-60 GHz proposed for future 5G applications using high-power photodiodes to excite the antenna elements.
