Integrated optical techniques offer the potential for miniature, low-cost, reliable microsystems for chemical analysis which may be exploited in monitoring environmental pollution, food contamination, state of health, and threats to security. Some approaches towards providing flexible multisensor platforms for a wide variety of chemical and biochemical species will be presented.
Planar optical waveguides are well established components for the interrogation of chemical processes at surfaces with, for example, total internal reflection fluorescence (TIRF) elements having a long pedigree [1] and surface plasmon resonance (SPR) sensors finding widespread use in biomolecular research [2]. The most important attributes of these devices are that the optical fields are confined to a submicrometer region above the solid surface of the transducer and that the light is delivered to the surface in a well-controlled way without passing through the bulk of the sample.
Materials and processes for integrated optics are faced with increasing demands from telecommunications and instrumentation applications. Progress in three aspects of novel materials and processes are described: titanium-diffused sapphire waveguides and lasers, interferometric excimer laser ablation of waveguide gratings, and surface studies by waveguide surface plasmon resonance.
