1. An array of light emitting devices formed on a highly resistive substrate, the array comprising:

  • a first light emitting device, comprising;

    a first n-type layer overlying a first portion of the substrate;

    a first active region overlying the first n-type layer;

    a first p-type layer overlying the first active region;

    a first n-contact connected to the first n-type layer;

    a first p-contact connected to the first p-type layer, wherein the first n-contact and the first p-contact are formed on the same side of the device;

    a second light emitting device, comprising;

    a second n-type layer overlying a second portion of the substrate;

    a second active region overlying the second n-type layer;

    a second p-type layer overlying the second active region;

    a second n-contact connected to the second n-type layer;

    a second p-contact connected to the second p-type layer, wherein the second n-contact and the second p-contact are formed on the same side of the device;

    one of a trench and an ion implanted region separating the first light emitting device and the second light emitting device; and

    a first interconnect connecting one of the first n- and first p-contacts to one of the second n- and second p-contacts.
