am i have to use optocoupler with ir2101 for isolation?

The HCPL offers isolation IF you REQUIRE it, the IR series do not REQUIRE isolation, it is only if your application Requires it that you use galvanic isolation.
The IR circuit will still function fine without any isolation on the control logic.
IOW if you use a IR charge pump driver and require isolation then an opto is used, otherwise, NO.
