This work reports a new optical platform that directly integrates optical fiber upon a planar substrate. The fabrication methodology uses flame hydrolysis deposition to form an optically dynamic as well as mechanically strong composite. The resulting platform is conducive to planar fabrication techniques enabling MEMS microstucturing; mechanically continuous on-chip-off-chip interconnects, removing the dependency upon traditionally vulnerable coupling methods; and is compatible with Bragg grating inscription, permitting multiplexed multiparameter sensing. Chemical sensing is demonstrated through on-chip evanescent field exposure and physical sensing is demonstrated through use of integrated microstructures.

High-precision imaging technology and its application are highly demanded for the enhancement of civil security. They are used to help prevent major incidents in railways or airports. In these applications, both small object detection and high-range resolution are key features. As far as the detectable target size is concerned, a high-frequency carrier is indispensable in radar systems. However, a radio signal with millimeter-wave (high frequency) suffers from large atmospheric attenuation. For example, the attenuation coefficient at 90 GHz is estimated to be 1 dB/km, while it is less than 0.1 dB/km in microwave bands [1]. Thus, the radar signal will have to originate from an area close to the target. Setting up a radar system with a synthesizer close to the target might not be desirable because a high-precision electrical synthesizer is generally large and consumes high energy. Radio-over-fiber (RoF) technology, used to transport the signal over optical fibers, is a promising candidate to deliver the millimeter-wave signal to the suitable point over a low-loss optical fiber cable. Radars utilizing the RoF technology have already been reported; however, digital signal processing in remote radar heads was required to reduce large transmission data [2, 3].

This paper describes an “active” version of a hermetic fiber-optic feedthrough for avionic transceivers; active means that the Tx and Rx versions of the feedthroughs include a VCSEL array or a photodiode array, respectively. The hermetic feedthrough is an assembly of stamped components that align all of the optics to precision sufficient for single-mode applications. A stamped micro mirror array bends the light beams 90 degrees so that optical fibers are arranged parallel to the substrate. Active hermetic feedthroughs can be attached onto the ends of fiber-optic jumpers to make an active, mirrored, optical fiber sub-assembly (AM-OFSA). AM-OFSAs allow transceiver manufacturers to eliminate complex optical alignment processes within the hermetic package and only require low-tolerance electrical connections.

The photonic extraction channelization technique generally experiences more attenuation than the suppression technique. Once a channel has been extracted from the spectrum, additional channels may be extracted from the remaining undisturbed spectrum but experience additional attenuation. The channels in this technique are heavily influenced by the shape of the optical filter.The photonic suppression channelization technique requires parallel optical methods to achieve multiple channels because each optical spectrum is manipulated to produce the desired channel. This technique generally experiences less attenuation than the extraction technique and the resulting channel are less influenced by the shape of the optical filter.
