“…Currently, several integrated optical technologies are developed with different technological platforms and material systems, including III-V semiconductors, silica, silica-on-silicon, and silicon oxynitride with processing based on standard photolithography [1]- [3], lithium niobate crystals modified with the titanium diffusion [4], as well as technologies based on sol-gel [5], polymers [6], and organo-mineral materials [7]. All existing technologies have their advantages and drawbacks but all have proven to be of preference for different applications.…”

This paper proposes the development and structural characterisation of an Er 3+ /Yb 3+ doped hybrid organic-inorganic material synthesised by a nonhydrolytic sol-gel process. By using a pumping laser diode at 980 nm, a typical Er 3+ luminescence has been recorded in the near infrared region (1.53-1.55 μm). However, the detected fluorescence was particularly weak compared to that generally observed in pure mineral materials, suggesting the occurrence of strong quenching due to multiphonon relaxation processes. To understand this behaviour, structural characterisation of both of the matrix and the local environment of Er 3+ ions were conducted employing infrared spectroscopy, nuclear magnetic resonance, electron paramagnetic resonance, and neutron scattering. These studies showed that the major phenomenon competing with the Er 3+ fluorescence is intimately associated to the strong vibrational modes of the organic species that involve multiphonon relaxation processes, resulting in energy dissipation within the host matrix.

“…For instance, LIF detection on a microfluidic system has been demonstrated as a promising approach for biological applications. One of the promising approaches to reduce the size of the optical detection system onto the chip device is the integration of buried optical waveguides [6][7][8] and optical fibers with microchannels [9][10][11]. Several ingenious works have been reported to use microfluidic devices integrated with buried optical waveguides for optical detection of biomolecules [12][13][14].…”

In this study, a new design of a controllable micro-lens structure capable of the enhancement of LIF detection system has been demonstrated, which can be further integrated with buried optical fibers on a micro-CE chip for sample separation and detection. Two pneumatic side-chambers were placed between a micro-CE channel and an optical fiber channel. The intervals between the side-chamber and the microchannel were used to form two surfaces of the controllable micro-lens structure. Deformations of the two surfaces can be generated after pressurized index-matching fluid was injected into the pneumatic sidechambers. The side-chambers can be deflected as a double convex lens to focus both the excitation light source and the fluorescent emission signal. The profile and the focal length of the micro-lens structure can be actively adjusted by applying different liquid pressures so that biosamples with a low concentration can be detected. Using low-cost polymeric materials such as polydimethylsiloxane, rapid and reliable fabrication techniques involving standard lithography and replication process was employed for the formation of the proposed chip device. Experimental results revealed the controllable micro-lens structure can be successfully deformed as a convex lens to focus the laser light source and the collected fluorescence signal can be enhanced accordingly. The power amplitude of excitation laser light can be enhanced by 5.4-fold. FITC dye and DNA markers were then utilized for micro-CE testing. The results indicated that the signal amplitude could be enhanced 2.5-fold when compared to the case without the activation of the micro-lens. According to the experimental results, the developed device has a great potential to be integrated with other microfluidic devices for further biomedical applications.
