“…Crosslinking occurs during the poling process which can lead to fabrication difficulties of the films as there are shrinkage, adhesion problems, etc. Several crosslinked systems have been investigated, but will not be discussed here [82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97] . Lately, there has been a lot of interest in high T g polyimides functionalized with NLO chromophores.…”

In this article we discuss the state of the art in the field of second‐order non‐linear optical polymers. More specifically, we highlight those results that we think made an important contribution to the field, combined with some of our own results. We start with a general overview of all the aspects involved in characterizing second‐order non‐linear optical polymers, from thin film formation and poling to second‐harmonic generation and electro‐optic measurements on such systems. Next, we review the second‐order non‐linear optical properties of selected polymer systems such as poly(vinyl ether)s, polystyrenes, polymethacrylates, main‐chain polymers and high Tg polymers like polyimides and polymaleimides. Finally, we discuss some new polymer systems that might become important in the field of non‐linear optics in the near future.

“…7 . 12 After the sample was heated at 100 'C for 40 h, the absorption spectrum showed only a slight change (see Figure 7). In contrast, the HMM/ANB sample showed an increase in absorbance at the Xmax after thermal treatment ( Figure 8).…”

A new class of all organic sol‐gel second‐order nonlinear optical (NLO) materials based on hexa(methoxymethyl) melamine (HMM) was developed. Two NLO active chromophores, 4 (4′‐nitrophenylazo) aniline (DO3) and 4‐amino‐4′‐nitrobiphenyl (ANB), were incorporated into the melamine matrices. The samples exhibited second‐order optical nonlinearity after poling and curing at 220°C for 30 min. DO3/HMM and ANB/HMM samples showed a second harmonic coefficient, d33 of 10.7 and 1.8 pm/V at 1064 nm, respectively. The temporal stability of both systems was studied at room temperature as well as at 100°C. Waveguide optical losses of samples at 633 and 830 nm were found. © 1995 John Wiley & Sons, Inc.

“…Further, enhanced temporal stability of second-order NLO properties in a poled polymer can be obtained when a certain degree of crosslinking is introduced [5][6][7][8][9][10]. Long term stability of second-order nonlinearities in a number of different crosslinked polymeric systems at temperatures higher than 100 'C has been reported earlier [6,9,10].…”
