We　propose　an　asymmetric　elliptical-hole　dual-core　photonic　crystal　fiber　(AE-DC-PCF)　for　hydrostatic　pressure　sensing.　The　transmission　spectra　of　the　AE-DC-PCF　under　hydrostatic　pressure　and　the　relationship　between　pressure　sensitivity　and　the　minor　axis　ratio　at　different　elliptical　ratios　have　been　calculated.　Our　results　show　that　the　AE-DC-PCF　has　higher　pressure　sensitivity　than　that　of　conventional　dual-core　photonic　crystal　(DC-PCF)　fiber　which　has　the　circular-hole.　Based　on　a　10　cm　fiber,　the　pressure　sensitivity　of　the　AE-DC-PCF　as　high　as　50.6　pm/MPa　were　achieved　at　1.55　mu　m,　which　is　higher　than　the　pressure　sensitivity　obtained　from　conventional　DC-PCF　(32.2　pm/MPa).　(C)　2014　Elsevier　Inc.　All　rights　reserved.
