For example, the Atacama Large Millimeter Array (ALMA) radio astronomy project is consist of an array of up to 64 antennas, and in order to achieve the unprecedented sensitivity and angular resolution, requires the local oscillator reference signal arriving at remote antennas with a maximum path length up to 18 kilometers must be stabilized under one picosecond [2].

The inherent low sensitivity and cross-talk to electromagnetic waves of fibre-based transmissions allow the introduction of these probes in the vicinity of the radiating antennas. These approaches lead to significant improvements since they will enable the calibration of the full RF system (starting from its radiating elements up to the RF processing unit), while they can operate not only during integration phases but also during operations.","PeriodicalId":347022,"journal":{"name":"2013 IEEE Avionics, Fiber-Optics and Photonics Technology Conference (AVFOP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130539749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There has been a steady increase in the capabilities of Ethernet, particularly a 100-fold increase in available bandwidth and the introduction of extra capabilities such as Class/Quality of Service (CoS/QoS) and Virtual Local Area Networks (VLANs.) Ethernet is non-deterministic and is not error-resistant and so there have been attempts to overcome these shortcomings. BAE Systems has developed the Deterministic Ethernet-based Fault Tolerant NETwork (DEFTNET) concept. Unlike Avionics Full-Duplex Switched Ethernet (AFDX), this represents a set of techniques that require no specialised hardware or software components in the end systems.

Analog RF photonic link applications often have critical sensitivity and linearity requirements, as such the noise figure (NF) and spurious free dynamic range (SFDR) are key performance parameters for these links. There has been considerable research dedicated to developing improved components and link designs to yield improvement in NF and SFDR. A single output intensity modulator based on an AlGaAs polarization modulation (PolM) design with half wave voltage Vπ≅3 V at 1 GHz, 3 dB roll off at 40 GHz, and optical insertion loss ≅3 dB has been reported and is commercially available. [1,2] If the linear polarizer at the output of this device is replaced with a polarizing beam splitter (PBS), dual complementary outputs similar to a dual output Mach Zehnder modulator (MZM) are provided. This allows for an intensity modulated direct detection balanced link (IMDD-BL) design to be implemented which provides multi-octave operation and common mode suppression (CMS) of laser relative intensity noise (RIN) to improve the link NF.[3] Such a IMDD-BL using a PolM, a single fiber from transmitter to receiver, and the PBS preceded by a polarization controller located at the receiver has been demonstrated at 2 GHz showing common mode suppression of RIN similar to a link using a standard lithium niobate (LN) MZM.[4]","PeriodicalId":347022,"journal":{"name":"2013 IEEE Avionics, Fiber-Optics and Photonics Technology Conference (AVFOP)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128007641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RF-over-fiber enables heavy stove-piped RF cabling tied to specific frequencies to be replaced by lightweight fiber that can be used for any RF frequency. Integrated photonics technology can provide the ultra stable oscillators needed for future systems, enabling today's specialized laboratory-only equipment to fielded in future systems. Photonic mixing and switching technology enables apertures to be used for multifunctions (like RADAR and communications) without having to change the “boxes” generating and processing the signals. RF photonic technology can enable broadly tunable receivers and transmitters that can provide wide instantaneous bandwidth (BW) anywhere over broad ranges of spectrum with a single receiver.
