A merocyanine dye, l-ethyl-4-(2-(4-hydroxyphenyl)ethenyl)pyridinium bromide (M-Mc, 2), exhibits a large spectral change according to the acid-base equilibrium [40, 41]. The equilibrium is affected by the local electrostatic potential and the polarity of the microenvironment around the dye. Hence, this dye is useful as a sensitive optical probe for the interfacial potential and polarity when it is covalently attached to the polyelectrolyte backbone. 

Potential-sensitive or polarity-sensitive dyes are known to optically respond to changes in their micro-environment such as changes in polarity or lipophilicity.

Helix is the most common higher-order structure of synthetic polymers such as peptides, polymethacrylates, polychloral, polyisocyanides, polyisocyanates, and polysilanes. Polyacetylenes bearing appropriate substituents also form a helix. Substituted helical polyacetylenes are promising candidates for enantioselective permeable materials, polarization-sensitive electro-optical materials, asymmetric electrodes, and hence their synthesis is currently under intensive research. This section overviews the synthesis and properties of helical polyacetylenes recently reported. 

Dickinson and Walt (119) recently reported the synthesis and characterization of a small four-member model hbrary L20 using two monomers in different relative amounts. The composition of L20 is represented in Fig. 11.27. The library individuals were polymerized at the end of a fiber-optic sensor, and a solvatochromic dye was entrapped in the matrix during the polymerization. The exposure of such a sensor to vapors causes the swelling of the four polymers, depending on their nature and composition, and a spectral shift of the polarity-sensitive dye. The two effects combined lead to a sensing region-specific temporal change in the fluorescence emission...

Figure 2 A scheme to obtain a photonic realization of CNOT gate with two independent qubits. The qubits are encoded in the polarization of the photons. The scheme makes use of linear optical components, polarization entanglement and postselection. When one and only one photon is detected at the polarization sensitive detectors in the spatial modes 63 and 64 and in the polarization H, the scheme works as a CNOT gate.

The additional components for achieving a PFS measurement are polarizing optics for manipulating both the illumination and scattered polarization states a polarizing beam splitter for directing orthogonal states into two detectors, and a means of forming three polarization-sensitive intensity correlation functions.

A diffractive optical element can be either transmissive or reflecting. It may be polarization sensitive or it can be insensitive to it. 

In Akkin et al, a polarization-sensitive low coherence fiber interferometer was used to measure -0.5 nm, 1 ms displacements in crayfish leg nerves. Calcite prisms are used to compensate for optical path delay between the nerve reflection and a reference cover glass. The authors suggested that the technology may allow noninvasive detection of various neuropathies.
