Abstract(in English) Pressure sensors utilizing silica based GRIN rod lenses are fabricated and demonstrated. Proposed method realizes inexpensive system because the system consists of low-cost devices such as a light emitting diode, photodiodes and a rod lens. In addition silica based rod lenses are attached to the fiber by fusion splicing without an adhesive, therefore the system shows little loss variation and high reliability. In this paper two ranges of pressure sensors, up to 200kPa and 10kPa, are fabricated with combination of bellows and a rod lens and high accuracy +/-0.2% are achieved for both sensors.
