In optical communication, information is transmitted using light signals. The range of frequencies used in optical communication is known as the optical frequency range.

Option 1: 103 -104Hz. This range is in the radio frequency range and is typically used for radio communication, not optical communication.

Option 2: 10®-10® Hz. This range is extremely low and is not used in any form of communication, including optical communication.

Option 3: 1013-1014 Hz. This range is in the infrared and visible light range. It includes frequencies that are commonly used in fiber optic communication, which is a popular method of optical communication. This option is the correct answer.

Option 4: 1010-1017 Hz. This range is in the microwave and radio frequency range. It is not typically used in optical communication.

Therefore, the range of frequency used in optical communication is option 3: 1013-1014 Hz.
