Abstract

There has been a great deal of effort on the integration of various types of devices on a single GaAs or InP substrate to form monolithic optoelectronics and photonic integrated circuits. Utilizing acoustooptic (AO) Bragg cell as the basic modulator, specialized integrated optic functional modules such as RF spectrum analyzers (IOSA), convolvers and correlators[1], space-switches[2], and matrix algebra processors [3] can be realized. Toward this objective we had previously realized GHz AO Bragg cells in GaAs waveguide, and devised the ion-milling technique for fabrication of waveguide lenses and lens arrays of high efficiency and near diffraction-limited characteristics[4].
