Abstract

Organic materials tailored to be transparent in the blue or near UV range are targeted as highly efficient frequency doublers for applications in the field of high density optical data storage1. Today, laser diodes emitting in near infrared region are commercially available at low cost. By doubling their frequency it should be possible to quadruple the information storage capability on the same surface. Other potential applications of such blue sources are in microelectronics, medicine, biology and information technology. Organic materials can be also used for the fabrication of tunable laser sources like OPO’s as well as for electro-optic modulation applications. For these applications, three major device-driven material requirements have to be fulfilled:
  1. i)

    broad transparency range. Typically, for blue conversion, the cutoff wavelength for linear absorption should lie below 350 nm

     
  2. ii)

    excellent optical quality

     
  3. iii)

    macroscopic non-centrosymmetric structure
