                      YBCO superconducting bolometric detectors is theoretically
                      and experimentally investigated. The effect of the device
                      thermal parameters on the theoretical total noise-equivalent
                      power based on background radiation, thermal fluctuation,
                      and Johnson noise is considered. By analytical optimization
                      of the total noise-equivalent power (NEP) of the device with
                      respect to the thermal parameters and radiation modulation
                      frequency, the maximum sensitivity and optimal thermal
                      parameters of the bolometric detector are obtained. Relating
                      device thermal parameters to the special case of the large
                      substrate dimensions, the optimum device geometry is
                      calculated. In addition, several devices with different
                      geometries are fabricated to experimentally test the
                      analysis. By performing experimental optical responsivity
                      and detectivity measurements for these devices, the effect
                      of the geometrical parameters on the maximum sensitivity of
                      bolometric detectors is also empirically obtained. The
                      analytical and experimental results are compared and
