In this paper, application of a Hollow Core Photonic Crystal Fiber (HC-PCF) as a micro-strain sensor has been demonstrated. Two different designs of HC-PCF with different core diameters (large core PCF and small core PCF) have been investigated for different strain levels ranging from 0 μɛ to 2000 μɛ at the wavelength, 1550 nm. High strain sensitivities of 3.71 pm/μɛ and 2.3 pm/μɛ have been achieved for the large core PCF and small core PCF, respectively. Also, due to the special air-hole structure of HC-PCF, the sensitivity of strain measurement remains unaffected of the changes in Surrounding Refractive Index (SRI)..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
