Abstract: Disclosed is a multipurpose shower head which can spray different amounts of water at different pressures through water spreading holes formed in three different portions thereof only by a simple operation of a lever, so that the use of a product can be very flexibly diversified according to a necessary purpose. Since the multipurpose shower head can very flexibly diversify the use of a product according to a necessary purpose, the multipurpose shower head can maximize the use convenience of the product and remarkably enhance the use satisfaction and value of the product. Moreover, purchase of only one shower head enables a user to not only take a shower, wash his or her mouth or use a bidet function, but also clean a bathroom without any problem. Therefore, the present invention can significantly reduce even the burden of purchasing a washing item of a bathroom cleaning item.

Abstract: An optical amplifier includes a passive waveguide region and an active waveguide region. The passive waveguide region is configured to receive an incident optical signal and adjust a mode of the optical signal. The active waveguide region is integrated to the passive waveguide region and configured to perform gain modulation on the optical signal received from the passive waveguide region by changing density of carriers in response to a current applied to the active waveguide region. Internal loss of the active waveguide region is adjusted to produce a resonance effect and thereby to increase bandwidth of the active waveguide. Therefore, the optical amplifier can have a wide bandwidth under a low-current condition.
