We show that accurate knowledge of the ratio r 13/ r 33 is critical to obtaining accurate values of r 33. We also derive an approximate analytic expression for the optical retardation as a function of the ratio of the off-diagonal to the diagonal components of the Pockels coefficients r 13/ r 33 and also the finite birefringence of the poled film. We derive approximate analytic equations to analyze the reflected intensity and verify the validity of these approximations when the analyzing wavelength is far from the absorption of the dye. The Pockels coefficient is measured by the ellipsometric reflection technique. We also find evidence that the dicyanovinyl hexatriene dyes in the copolymer are interacting with one another, causing a relative decrease in the copolymer’s electro-optic efficiency compared with its value as a guest–host in poly(methyl methacrylate). The largest r 33 is observed for the copolymer containing the amino donor, hexatriene linkage, and the dicyanovinyl acceptor group with a value of r 33 = 18 pm/V at 140 V/ µm at a wavelength λ = 1.3 µm.

r 33 are reported for dyes as guest–hosts in poly(methyl methacrylate) and 50/50 copolymers with methyl methacrylate. The Pockels coefficients r 33 of four dyes for electro-optic applications are reported, including ones with stilbene, butadiene, azo, and hexatriene linkages between the charge donors and acceptors, with the charge donor being the amino group and the acceptor groups being the nitro and dicyanovinyl groups.

Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.

Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.

Use these formats for best results: Smith or J Smith.

For best results, use the separate Authors field to search for author names.

Use quotation marks " " around specific phrases where you want the entire phrase only.

Question mark (?) - Example: "gr?y" retrieves documents containing "grey" or "gray".

Asterisk ( * ) - Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity".

The film, based on the real-life events of this heroic feat, tells the story of the leaders and soldiers who used their instincts, fortitude and bravery to overcome the odds. Keep it simple - don't use too many different parameters. These properties make BBO the choice of NLO crystals for a generation of coherent UV light by higher harmonic generation using Nd:YAG solid lasers and near. MIDWAY centers on the Battle of Midway, a clash between the American fleet and the Imperial Japanese Navy which marked a pivotal turning point in the Pacific Theater during WWII.
