description The utility model relates to a volatile organic compound sensor based on a high birefringence photonic crystal fiber environment. The two ends of a high birefringence photonic crystal fiber are aligned with two single mode fibers respectively; small intervals are formed between the two single mode fibers, so that the two single mode fibers are put into an air chamber (which is provided with an aligning system and a height-adjustable platform through a special design); the other ends of the two single mode fibers are guided out of the air chamber, and optically connected with two ports in one side of a 3dB coupler respectively to form an optical fiber environment; and the two ports in the other end of the 3 dB coupler are optically connected with a broadband light source and a spectrograph respectively. In order to solve the problems that an existing volatile organic compound sensing technology is complex to manufacture and high in cost and has difficulty in multiple measuring and micro detecting, the utility
